Fit for winter.

The hardest part about getting out for winter base miles is often just that — summoning the motivation to get out the door. When motivation is in short supply, excuses never are, and the time required for gathering and donning the necessary kit for temperatures around 30 degrees Fahrenheit can occasionally be enough of an inconvenience that we leave the wheels hanging for the day. The LL.milleTights_s7 Bib Tights for men are Assos' thoughtful solution to lazy kit syndrome, designed to pull on fast to eliminate as many barriers between you and your base miles as possible. By extending considerations of craftsmanship beyond the act of riding to include the time before you're in the saddle, the LL.milleTights may represent a first for even the innovative Swiss manufacturer.

We love the indescribably perfect fit of Assos' top-end LL.bonkaTights, which virtually disappear once you pull them on, but achieving that disappearing act requires a lot of patience and a little bit of struggle to situate the bibs just so. The LL.milleTights, in contrast, feature what Assos describes in typical, camel-case style as comfortFit. Near as we can tell, comfortFit means a slightly more forgiving cut, especially through the bibs and rear yoke, which makes for a much quicker application that you don't necessarily need to be 100% awake for. While this may seem like a minor luxury, it certainly appeals to us on frigid winter mornings when we're already fumbling at the coffee pot and the floor pump and one more impediment may spell a preemptive end to the ride.

Of course, this is still Assos, so comfortFit doesn't mean club fit. The attention to detail that made Assos' name is evident in details like the articulation down the back of the leg, which strategically tapers and combines panels of material for a fit through the back of the knee that's every bit as bunch-free as the LL.bonkaTights. Even the reflective strips on the back of the legs are only attached at the ends, as sewing the lengthwise sides to the tights would compromise the stretch and fit of the fabric.

The materials themselves are both of the RX genus, which hits the usual cold-weather benefits of a brushed inner face for insulation and rapid moisture transfer. The leading panels are RX Heavy, an all-new material that doubles up on thermal protection with two layers at the knee, thigh, and hip, and doubles down on moisture control with Assos' water-resistant treatment. The back of the legs are made from the lighter, more breathable RX Light in order to regulate the microclimate's temperature while evacuating sweat and water vapor to ensure that a single hard interval won't condemn you to a clammy chill for the rest of the ride.

The LL.milleTights are finished with the long-distance Mille chamois, which has more surface area and less elasticity than Assos' summer-weight racing inserts. The Mille makes for a more stable pedaling platform across long base miles when your body position remains relatively static. It's still built with Assos' goldenGate technology, so the unattached center sides allow the chamois to move with your skin rather than against it, and it's also got a supportive pouch-like construction at the front to prevent awkward podium moments while waiting in line for a mid-ride coffee.

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Large

I tested these on my first ride in what I knew would be the low end of the temp limit on these based on previous reviews. In 20F with not much wind these were good. Anything much lower than 20F I will want something w wind block material like my PI Amfibs. Anyways, I was out for a little over an hour. When I took these off only my upper hip area was a little red from the cold but I didnt really feel any cold areas while riding. So I would say the range(for me) for these are 18F-45F. The lower end of the spectrum in low wind(no wind block material on these) for 2 hours or less but as you approach 30F I am sure these will be fine for being out several hours. Fit is great. These have more compression than I have been accustomed to compared to my PI Elite thermal and PI Amfib bib tights so at first I thought these were too small, but after the ride I realize they are spot on. Just know if you are accustomed to a different brand/model that does not have much compression, these are different in that respect. I love these so much that I am ordering another set of Assos bib tights for milder/mid range temps with slightly lighter material(HabutightsMIlle_S7) Should give similar fit for more mid range conditions. I feel if you get any option of the Assos bib tights you will probably never want to buy any other brand for bottoms going least that is where I am at!

The last thing I will mention is the chamois. Most cycling bottoms are defined by the quality of chamois and these do not disappoint in this regard. It is strange to look at at first because the chamois is partially detached from the outer of the bib(I believe they call this "Golden gate"). I am not an Assos expert but I believe this allows the pad to move with your body rather than your bottom moving over the pad. In theory this drastically reduces friction compared to a normal pad where that is generally completely sewn in. This pad works. So comfy.

BOTTOM LINE= If you buy these or other Assos bottoms you will LOVE them!

Runs small

  • Familiarity: I returned this product before using it
  • Fit: Runs small
  • Size Bought: XL

Ordered the XL. I'm 190 lbs, 6'0". 38" waist. Not a huge person. Usually wear an XL or L in bike shorts or tights. But this XL was extremely tight. I'm returning for an XXL. I hope that's cut significantly larger. (But won't be shocked if I have to go up to the 3XL.) These do seem like they'll be very warm for riding in the 40's down to at least the mid-30's.

Great cold winter tight

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

I've used this tight in 28 *F with 15 mph head winds and it has kept me warm over a 2 hour ride. I think that is about as cold as it can go but I was very comfortable at that temp. It is well built with a great chamois.

Absolutely sublime

  • Fit: True to size

What makes these bibs great is that you don't feel like you're wearing anything at all. After comparing these with many other bib tights, I realized that many of them had seams around the knees that made them seem comfortable when standing, but rubbed a lot when pedaling. If you're going to be cold, spend the extra money and get these.

Winter riding pajamas

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

As I keep pushing my riding threshold down to colder temps, I had to keep expanding my riding wardrobe to accommodate. I picked up these tights with an eye toward gear for high-intensity rides down to 20 F. I believe these tights are just the ticket.

Of course, I haven't actually ridden these in proper 20-degree weather yet. It's been much colder. In the first few rides with these, ambient temps were in the low-20's, but with extreme winds that put the windchill/"RealFeel" in the -5 to 5 degree range. And that's before cruising at 15-25 mph. These bibs have done a good job keeping me reasonably warm for an hour or so, which I believe will translate into comfortable extended rides at 20 degrees in more normal conditions.

The feel of these tights is totally plush -- like riding in your PJs. I love not having zippers or stirrups at the ankles, and they are definitely not needed here. The fabric on the front is more wind-resistant that the fabric on the back, and Assos goes futher by adding a second layer of fabric in a peanut shape that runs from below the knees, up the thighs, and around to the hips. I didn't get any bunching behind the legs at all. One of my key concerns was finding tights that would block wind from the crotch area, and these are decent with that. On the most super-frigid day -- which was admittedly far colder than what these were intended for -- I did get some serious chill in that area as well as the front of the hip area, where there is no double-fabric. In fact, it was so cold I could feel a sharp sting that told me exactly where the edge of the double-fabric was around the whole tight. That said, I think these will be fine down to "normal" 20-degree weather.

On size, I run an XL in Castelli shorts, but find a Large fits me very nicely in these tights and the NeoPro bib shorts to avoid some bagginess at the knee -- same as a prior reviewer.

Update: Have ridden these a couple times now in 30-40 degree weather, with wind and light rain, and they are toasty in that range.

Questions :

1. I'm a Medium on the Equipe and Neo Pro bibs - will I fit in Small in these? There's great emphasis on its "generous" fit.

2. How's the windblocking on these? I know it says it has a heavy fabric at the front that doesn't really equate to windblocking properties.


I would go with the same size as your NeoPros, I have both and the fit seems comparable to me. If anything, these seem to fit slightly snugger than my NeoPros.

Not particularly good. Took mine out for their maiden ride yesterday. 30*, cloudy, light wind. 30 miles at fairly brisk pace. Front of legs fine, for the most part, but felt the cold on fast downhills. Butt, hips, and privates cold.

Bought them to be my cold, cold weather tights, i.e. 15-25* F, but they’re not as warm as a pair of Giordana FR-C I have, and won’t be up to the task. Fit fine, comfort fine, typical Assos quality, but a disappointment in terms of what I bought them for. Had asked Assos whether they were as warm as Bonka tights and they said they were, but bulkier. As I disliked/had no use for the neoprene bottoms on the Bonkas, I went for the Mille. I suspect I got bad advice.

Do these have wind-blocking fabric in the crotch?

They have the heavier RX fabric all through the front of the short.

Perfect pants

  • Fit: True to size
  • Size Bought: Medium

While not top of the line, this is a no frills but excellent class winter bib. Just as described, wear it for your daily rides when you dont live in the Swiss Alps but in NYC.
Warm, with some water repellent ability, it fits, doesnt move, and lets you ride comfortably in cold temps.

Great. Reserving 5 star for Habu

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

This bib tight is a good value. What you're wondering is, should I get these, or spend more and get the Habu. They are both very warm and are effective at blocking cold air. They both have an updated chamois (not sure if they're identical or just similar). They both go on very easily. The main difference I notice is that the Mille have a simpler construction and a different, more basic fabric that is very soft but noticeably thicker than the waffle-style fabric on the Habu. The thicker fabric on the Mille is more constricting, sort of like your mom bundled you in one too many layers before you went out skiing. It also detracts from the feel of the legs/thighs as they move next to the saddle. If I could get just one pair I'd get the Habu. The Mille is a great backup pair, especially since you will stretch your dollar further. But that's comparing Assos to Assos. The Mille are still probably better overall than most other brands of bib tights out there.

Excellent mid-winter tights

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: Large

I bought these because I needed a go-to pair of winter tights for the 25-35 F range. They are terrific in that band -- keep legs toasty yet allow some (imperceptible) passage of air so that sweat doesn't build up and you don't overheat when a 25 degree morning becomes a 40 degree mid-morning. I've not yet used them at 20 degrees but expect that's probably about the lower bound (and I have some Assos Fugu for colder temps). I expect to get a lot of use from these in the Boston winter. Sizing runs true (I'm 6 feet even, 165 pounds -- Assos says to buy large at that H/W and I did -- even though I have to buy medium in their shorts to avoid bagginess at the bottom of the thigh).

What is the recommended temperature range for these tights?

Best Answer

Per my review, optimal is mid-20s to mid-30s -- and you should be able to go a little above or below without a problem.
