T.laalaLaiShorts_S7 Lady Bib Shorts

The number of claimed firsts in Assos' history is astounding. First skinsuit (1976), first Lycra cycling shorts and bibs ('76), first multi-density chamois ('88 — maybe our favorite "first"), first leg grippers ('98) — the list goes on. While they're not another industry first, the T.laalaLaiShorts_S7 Lady Bib Shorts do represent the first bibs in the women's S7 line. For those of us who have been clinging to our long-suffering T FI.Lady_S5 or the skinsuit-esque tB.laalaLai_s5, the T.laalalLaiShorts will be received with no less revolutionary fanfare than those other firsts.

It took the company six years to design the men's S7 line, and in the seventh year, it comes to women, too. And it didn't come alone. It's brought with it a host of features that were pioneered in the men's S7 shorts but refined for women. Instead of the typeA.430 and 434 material used in our old Lady Assos bibs, the T.laalaLaiShorts are made of the same type.439 material used in the men's T.equipe and T.cento shorts. The material is laid out in a pattern designed to accommodate a woman's body in the saddle, and — though the shorts shaping is the result of a completely independent design process — the type.439 material provides the same functional benefits for women as it does for men.

Specifically, the material is breathable, moisture-wicking, and quick-drying. All of which are obvious and, at this point, just assumed features. The material's real shine lies in its compression, which Assos engineered to provide an asymmetrically compressive hold that stretches more around your body rather than vertically. While unmediated, all-way stretch is a nice element for general comfort in cycling shorts, Assos' targeted, direction-specific stretch ups the ante by balancing compression, yield, return, and support for a cycling-specific application. This balance allows uninhibited pedaling while further reducing the fatiguing oscillations caused by road noise vibrating through the muscles of your engine.

This targeted fit construction also means that, while you're rifling through your apartment looking for your sunglasses and a CO2 cannister before a ride, the shorts aren't going to feel completely comfortable. But. When you finally clip into the pedals and stretch out to the bars, your body will click into the T.laalaLaiShorts. This Advanced Ergonomic Pattern Design (AEPD) fit is ever-present with the S7 line, and it's been further enhanced by its new Y7 bib strap design. While the S5's straps were spot-on from a comfort perspective, this latest generation's straps give wider berth to the throat for better support. For example, while positioned over the hoods or down in the drops, traditional bib straps generally create a gap away from the torso between the collarbone and upper hips. But by aligning the straps outward, more along the obliques, the straps hug the torso, mimicking the body's movements without any gap, regardless of on-the-bike positioning.

Also like the men's S7 models, the type.439 material used here is finished with an iceColor application, which effectively reduces surface temperature in dark fabrics. Unlike the men's versions, though, the women-specific bibs include a front buckle. The new model has been updated with a magnetic connection that Assos claims is more comfortable than that on the S5, but we never really had any complaints about the outgoing system. The obvious improvement is in the mechanism's engagement, which clicks into place with the same intuitive ease that the your body clicks into the Assos fit.

As the first women's bibs in the S7 line, the T.laalaLaiShorts also introduce lady racers to the joys of the purple chamois. As with all of the S7 collection, the insert rocks Assos' new amethyst color, a purple hue chosen to pay homage to the clothing of Roman emperors, English monarchs, and members of the Japanese aristocracy. The chamois is designed according to the same philosophy of progressive support that informs the men's amethyst inserts but with a topography specific to female anatomy. The material's high stretch, high return properties allow it to compress and expand in coordination with the surprisingly complex pattern of movement that pedaling produces in the ischial and perineal areas. This effectively "fills the gaps" that other inserts leave during a pedal stroke, reducing the number of instances when the skin in these sensitive areas separates from and reencounters the chamois surface. The result is less chaffing, because the chamois moves with your skin rather than independently of it.

Assos also rethought the way a traditional chamois is attached to the shorts, developing yet another avenue to help reduce friction and irritation. This led them to what they are calling the goldenGate, which involves interrupting the stitching along both of the chamois' side panels, allowing a more "three-dimensional" freedom of movement in this sensitive, rotational area. But if that weren't enough, Assos went ahead and extended the chamois' thinly-padded sides over this short-to-chamois junction, making the transition against your skin as smooth as possible.

My favorite pair

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Large

I've had my Assos Lalalai for over a year. Long lasting, durable, the right compression, the chamois is great. I've used it for short rides, long rides, hot weather. These bib shorts are worth every penny.

Almost everything I want a bib to be

  • Familiarity: I've used it once or twice and have initial impressions

I was looking for a bib that I could wear for my double centuries so I decided to try this because it is highly recommended by randouneers. I emailed assos for my size and they recommended small. 5'5, 128 lbs, 38 hips. I've used it on my 50 miles rides ( with specialized power saddle ) and no pain/chafing/saddle sore at all. I love the compression. No sausage legs. This actually makes me look like I'm wearing spanx. Chamois is not too big and bulky. Just perfect. The magnetic clip is a very good idea, I can slide it down alright however I need to remove my helmet to get the strap over my head. Putting it back i needed to try several times because it gets twisted at the back. I can remove my jersey and put it back nice and flat but it defeats it's purpose. If assos can put the magnetic clip at the back like the rapha and specialized bib, they would have the perfect bib in the world.

Unanswered Question

How long is the inseam on the small?

Comfortable, happy butt!

  • Familiarity: I've put it through the wringer
  • Fit: True to size

These bibs are great. So many bibs that are on the market chafe or have chamois that are like diapers. This chamois forms to fit your body and is soft and comfortable. I've worn these on long and short rides and have been very happy.

The only downside for me is the weird noose strap. Not a fan, but you can ignore it once it's on.

Great Chamois, Weird Strap

  • Familiarity: I've used it several times
  • Fit: Runs small
  • Size Bought: XL

So. About the straps, let's just address that off the bat, eh? I'm sure some folks like it, but oy, I am not a fan. After a couple decades of playing bikes, I have perfected the strap-scoot-through of the shirt sleeve, and feel fine about that situation. The snap thing in the front of these bibs I find a bit cumbersome and weird to put on.

Moving on, the chamois itself is *very* good. Like wear-for-many-hours-right-away comfortable. I tested these out over three days of riding in Southern Utah and was stoked about the comfort over many long miles of canyon rides. The length felt just right to me, and they wick perfectly.

Assos does run small. I wear an XL in these bib shorts, but a large in Castelli, Giordana, a medium in Machines for Freedom. I am 5'6" and 148lbs (ish).

Curious to know what’s the inseam length on the XL bibshorts?

Best Bibs Ever For My Bike Rides!

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: Small

I purchased these bibs for my longer rides but now they are the only thing I want to ride in! I bought the shorts as a backup but the bibs are still my go to pair for every ride! I have at least 6 other brands of shorts and bibs (Pearl Izumi, Specialized, MuMu, Safetti, etc) and was going to save these pricey gems for the long rides but they are so much more comfortable than all my other pairs that I can't bring myself to use anything else on a serious ride. If I dressing for an easy spin for an hour or so and under 30 miles I might force myself to put on something else but then I ride hard and afterwards always notice a little tenderness and ask why did I even bother? That said, there is a short learning curve but it is worth it!
The fit should be snug because these are compression garments to help your circulation! That's why they go down your leg a little farther than some but it helps your quads and also sun protection. Get used to a snug fit and don't buy baggy. They stretch in all directions like crazy so you will see happy campers of 5'8' at 115 wear a small, 5'2" at 110 wear a small, and 5'11' at 148 wear a medium. The front buckle attachment pulling the bibs up at center front gives a very flattering midsection support without any shoulder pressure or chest excursion breathing pressure. For rest room breaks, the unbuckled strap stretches over my helmet and glasses. To go without removing jersey just let it slide down the back and grab from base and hold it or tuck into grippy pant leg. (You don't want it to hit the floor or worse!) To thread back up just use one arm behind back to bring to neck where you grasp with other hand, be sure still not twisted and bring back over head. If you have tight shoulders, you might want to practice the yoga position Cow-faced Pose / Gomukhasana. Or if you can't do this you might have to take your jersey off to put the bib on at rest room breaks. I sometimes unzip the full zip jerseys, hang up then no worries about passing under the jersey. I ride in heat and high humidity so not a problem to remove jersey if necessary. Quarter zip jerseys are not the greatest for speed stops or when first practicing with these bibs.

The black color reflects sun and is cool and evaporative to ride in. The chamois seems more breathable than any other I have experienced! But the pad is the key feature; the un-sewn floating center area just glides along with the pedal strokes and the multi-density cushion is cloud-like. I have ridden 170 miles in one day and many many 100 mile days and now almost all my shorter rides over 4,000 miles easily on these shorts and they look brand new. On multi-day rides, I must hand wash and the odor control is still fabulous; I have other shorts that will not hand wash up as well. That's why I'm going to purchase another pair of the bibs. What else can I say? I don't really like the excessive packaging, Assos button, or the pink tag in the middle of the rear butt seam, but these are minor branding items and have no bearing on performance. These are the best bibs I have ever found and I hope Assos keeps making them! I am not being paid to promote T LaaLaLai S7 bibs!


  • Fit: True to size

Bought these for longer rides but the unsewn chamois bunches up while riding and causes painful hot spots on longer rides. Was wearing my club kit on shorter rides, but now doing any ride over 40 miles I relied on these and hoped these bibs would be as wonderful as so many reviewers mention, but these don’t work for me. Wished I had known as would have returned while I still could. Waste of money.

Hey Monique,
If you can give Clifton at Competitive Cyclist your email and he share it with me, I'd buy these from you. I'm in the process of getting more pairs of these bibs since they are all I want to wear anymore! I take a small but would try a medium if you still have them and ever read this! :). Arlyne

These are a gamechanger

I love my Castelli Velocissimo shorts but these are now my go to for long rides. The chamois hits in the all the right places and I rode 50 miles in comfort. The bib fit is great and I like the magnetic opening. I'm 5', maybe 105lbs (I got a small) and these weren't too long on me which is sometimes a problem. I'm going to be watching for these on sale. I also ordered the shorts and they didn't fit as well as the bibs. The price was steep but with the 20% off it wasn't awful and honestly I would have paid more for the comfort they gave me.

Chamois > Bib Strap

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

These pair of shorts have one of the best chamois I have ever ridden with. They feel a little like a diaper the first time you try them on but when you get on the bike it is one of the more comfortable rides.

That being said I absolutely hate the bib strap. They unbuckle in the front but that doesn't matter too much because it is still around your neck so you have to finagle yourself out of it underneath your jersey. Seems odd as to why they even have a buckle. This doesn't make that much of an impact to the feel of it while riding so I use them quite often.

Good chamois, bad muffin top

  • Familiarity: I've used it several times
  • Fit: True to size

This is an update to my previous review. I purchased these from another retailer and couldn't return them so I've continued using them. Still the best chamois, but I hate them. They are uncomfortable and look like h*ll--think major muffin top and accentuates the pooch . To make matters worse, the stupid magnet harness thingy is completely useless (half naked in the woods anybody?) and the magnet has ended up IN the toilet twice when I'm trying to use the bathroom. Gross!

If they were $50 I could deal but for the price, the engineering sucks.

Amazing design and execution

I am thrilled with this purchase. I have put 500+ miles on them already and am delighted to compare them to the only other bib shorts I own, the Pearl Izumi Pro Escape bib shorts. These two shorts have in common the goal of letting you go to the bathroom without having to remove your top. There is no doubt, the Assos shorts win in this regard. The design is amazing. You unclasp the magnetic clip in the front, and the bib straps lift right over your head+helmet. Then you let them fall down the back of your jersey, do what you need to do, and when you're ready you just feed them back through under. It took me 2 practice times and now I can do it in just a few seconds without any twists in the straps. Once over your head, re-clasping in front is a breeze. In contrast, the Pearl Escape requires you to do bra-style clasps in the back, vertically not horizontally like you're used to with bras. Once I'm sweaty, I find this so difficult to do that I just go ahead and take off my jersey anyway as if the clasp in the back isn't even there. So that makes it pretty useless for me. Anyway, in terms of convenience for ladies and the inevitable potty breaks on long rides, I do not think any other shorts compare to Assos.

Now, for the MORE important thing which is comfort on rides. This chamois is the best quality I have ever felt. It has good coverage, and this made me nervous as first because I wondered whether the large chamois would cause chafing on the sides. It does not, because the thickness is tapered and because they do not stitch the parts where there is possibly friction. I ride on a minimal-padding Specialized racing saddle, and am delighted with the performance of these shorts even on 100 mile rides.

As to sizing, I am 5'2" and was 135 pounds when I purchased these shorts, I am 130 now. I really struggled with what size to buy because I have been burned by way-too-tight cycling clothes in the past. However, I followed the reviews here, went ahead and ordered a medium. They are perfect, and I've read much taller women who weigh more say the same thing, which I can only attribute to the fact that the fabric is very high quality and stretchy. It also is not binding at the thighs, so it does not cause that sausage effect for me. I admit, I would love it if these shorts were just a couple of inches shorter, but they are actually pretty flattering and they stay put even though I slather sunscreen just a touch underneath the hem before I fold them down (I am too nervous to leave a crack of unprotected skin)!

Amazing design and execution

Couldn't wait...but

  • Fit: Runs large

I've been wanting Assos bibs for a long time, but these will be returned. The sizing was too generous, and while I could have sized down, they are just too long for my liking. Bummer. I know Assos is supposed to be the best. I will remark, that at my brief try on, I was surprised they didn't feel better in materials and construction. I have other Italian made bibs that seem much higher end quality and are about $50 less.

Best chamois, starting to love the strap

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: Medium

This chamois is by far the largest chamois I have ever worn. It really covers a lot of surface area and offers a very comfortable ride. As far as the chamois goes, at 8mm thick, its not the thickest chamois I've every worn (Giordana NXG bibs is a little more padded) but it is super super comfy. Once I put these bibs on, I dont have to think about them moving around or anything while riding. The inseam is pretty long, even on me, and the shorts go to 4 inches or so above my knee (I am 5'11'' 148lbs and wear a medium).

I will add that the straps down the front made me a little nervous they would be uncomfortable but I honestly love them. The first ride it was a little weird starting out to have that strap right down the center of my chest but after the first bathroom break, I was sold. Pulling off the bibs to answer natures call has never been easier. There is definitely a little fumbling with the straps on the back when pulling back up but overall, it is much easier than completely undressing like with other bibs.

I will also add that it is important to note that these bibs are meant to fit *while riding a bike* which means that they might feel too tight or fall below your belly button when standing straight up but once you are bent over the handlebars pedaling the bike, the fit is excellent. I would highly recommend these bibs to all my friends and Ill probably be buying a couple more pairs for myself!

UPDATE: Rode for 7.5 hours yesterday in these bibs and holy cow they were amazing. Assos's motto "suffer in comfort" is so true. The last thing I want to think about on a long epic ride is chamois or bib discomfort and these bibs get the job done and do it well. Seriously incredible pair of bibs. Day after the ride and I have zero saddle sores or rear end pain. I'm honestly going to buy 3 more pairs. Please reach out if you have questions, I recommend these bibs over all the others I have ever worn/ owned! sedwards@backcountry.com

5-star chamois, 1-star bib strap design

  • Familiarity: I've put it through the wringer
  • Fit: True to size

The chamois is the star of these shorts and is, as expected from Assos, incredible. I could wax poetic about it for a while, but suffice to say it's really, really comfortable and right there with some of the best chamois I've ever worn. Attached to that chamois, the shorts' fabric is an ideal blend of stretch and compression, with enough breathability to handle summer days without feeling like you're falling short on cool spring mornings when paired with knee warmers.

That said, the bib strap design is just awful. It's difficult (and super awkward) to stretch overhead to actually get on, and still requires removal of all the top layers at mid-ride rest stops (it would take some extreme shoulder flexibility otherwise). Once on, the plastic clasp sits uncomfortably against the skin, so a baselayer is a must with these shorts. The straps also sit close in at the neck, so they show if you unzip your jersey at all.

Overall, if Assos would make these shorts with a traditional bib setup, they'd be my top choice for any day on the bike. The leg length is on point, the hems stay in place comfortably, and the chamois is really as amazing as Assos says it is. They're still my go-to in baselayer/knee warmer weather b/c of the shorts construction, and are definitely worth a try to see if you can get past the bibs.

Side note - I've talked to a few riders on the shorter end of the height spectrum who are completely fine with the bib design, so it may have something to do with height. The bibs may be less obtrusive if they don't have to be stretched as much.

On sizing - I'm 5'8", 115lbs and have a size small, which is a little bigger than I'd like in the shorts, but they work. An extra-small would be ideal if the bibs were normal or a little longer.

I agree with this review. Rode 7 days through the Greater Yellowstone Eco system. 25,000ft climbing over 500miles. Had two pair of Assos plus other bibs but would wash Assos at camp because of the comfort they provided. Amy husband got saddle sores...not me
