The single unit.

Instead of being shorts and undershorts, the Alp-X Pro 2-in-1 Shorts from Gore are a single unit where the bib straps are connected to the shorts, making them extremely lightweight and unfussy. No waistbands to get in the way, no exposed back, no tearing of road-specific Lycra.

The chamois that Gore uses here is their Alp-X Pro Men’s insert. It has been specifically designed for long and demanding off-road rides. Using a 3D construction to enhance moisture management, the shape with the central channel accommodating the male anatomy will increase bloodflow and reduce the possibility of getting numb. It is a super-high density insert that has padding specifically placed to provide the ultimate protection and cushioning support.

The outer shorts material is a highly functional mix where you have abrasion-resistant material around the inside of the leg, the saddle area, and the sides so that you will be protected from the occasional crash, and you won’t have to worry about snagging delicate spandex when you plow through some branches. Splash-resistant fabric on the back will protect you from getting soaked on wet or muddy trails, and mesh inserts in the front and back of the outer shorts provide the ventilation to help air things out. And a side mesh pocket will give you a place to stash your energy bars or gel packs for easy access.

The bib straps are a full mesh construction to prevent you from overheating by making it easy to ventilate. A radio pocket at the back of the uppers has been provided either for race situations, or so you can have your iPod there when you are training. Reflective logos have been placed on the back and side, so that you can alert drivers to your presence on the road if you are rolling home late in the evening after a long day on the trails.

Really nice shorts

  • Fit: True to size
  • Size Bought: Medium

These are great shorts to bridge the gap between traditional spandex and baggies. The fit and the construction are both good. The chamois is a bit thick (as compared to most of my road shorts) but not so much so to feel like a diaper. The extra layer from the outer short helps to add a bit of warmth and keep you dry.
All told I am very happy with these

I can't find the side mesh pocket that is mentioned in the description. Is the description wrong (it even says there's a side mesh pocket on the Gore website) or am I just blind? I've turned them inside out and looked at every seam with no trace of a pocket other than the radio pocket on the back of the bibs...

There is a mesh pocket on the right leg of the inner/spandex short.

Very Impressed

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

I have been slowly moving toward tighter fitting shorts as I don't see much practicality out of the long baggy ones on my local trails that aren't very sketchy or downhill oriented. These shorts definitely lean for more XC riding but I love them for my trail riding because I'm climbing and pedaling a lot. They feel very well made, high end and I plan to buy another pair.

Small negatives: I can confirm a swishing sound when riding, the actual short rides up the leg when on the bike, exposing the chamois on the lower thigh a little.

Best of Both

Clever, functional design. Top quality bib shorts built into nice light, ventilated baggys. Cross country style (not longer enduro type) look with the comfort of your finest road bibs.

Nice, but a compromise

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

I'll say it: I'm a mountain biker, and I'm a lycra guy. I used to be a baggy guy when I was younger, but I've pretty much come to the conclusion that I don't see any benefit to baggy shorts while riding a bike the way I ride one, and I see a whole lot of drawbacks. It doesn't help, in my opinion, that most mountain bike baggies look like leftover stock from a mid-90s Hot Topic.

So anyway, the point is I don't like baggies. But it does feel a bit odd if you go out on a group ride and then a beer with a bunch of guys wearing baggies, and you're wearing your XC race kit. So I thought these would be a good compromise, and that's exactly what they are, in ways both good and bad.

First of all, they really are nicely made. The construction and fit are good, they are just as tight when you pull them on as any Italian roadie bibs, and the pad is very nice. However, the overshorts are pretty slim-fitting, and aren't baggy at all when you're on the bike. They ride up just a touch--though not in an uncomfortable way--and end up sitting tight against your thighs. They're not restrictive in my experience, but they end up being snug. For me, this is a good thing. There's no droopy crotch to get caught on your seat or leg openings hanging down around your knees. But if you are actually looking for something that looks baggy while riding, this ain't it.

But they're also not just lycra bibs. That extra material is there, and it creates a constant swishing sound while pedaling. Like, every pedal stroke. After a little while you kinda stop noticing it, but it actually makes me wonder if it'll cause premature wear.

So, all of that said, I do like them and I'm glad I bought them (on sale). They do fulfill their purpose for me, and I tend to wear relatively slim-fitting shorts that hit me above the knee for casual wear, so I like the way these look when you get off the bike. I also like that they bring t-shirts into play as riding apparel, because sometimes it just feels good to wear a t-shirt.

So yeah, I do like these. But you have to know what you're getting when you buy them.

Dustin, they actually designed this so that it would be tight when sitting, and slightly baggy when standing. That was the whole point of the design, as some of us don’t want our shorts baggy while riding, and yet the convenience of not lounging in tights postride.

Expensive, but worth it

While expensive, these are the best for anyone who likes to wear bibs under shorts. Sooooo much less bulky and cooler, both temperature and the look.

When I first saw this product the first thing that came to my mind is:"Finallyyyyy" .
An amazing bib loose-fit shorts in one. Light weight, very stretchy, heavy duty, super comfy, MTB shorts.
I have raced XC MTB for several years, and I ride all mountain trails, and these shorts can be worn for both and I can say for all mtb activities, you can even wear them for commuting. They look great, fit great, you almost forget them while riding.
My first empression when I got them was: WOW very well done, you feel the quality of Gore Bike Wear.
When you put it on it feels like its made for you.
When riding you feel like wearing only bib thights, they don't get stuck in your saddle when moving forth and back, up and down.
I liked them so much I bought a second pair, and I think I will never wear my old shorts again.
I defenetly recommend .

Great alternative to regular bib short

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

I typically have worn a mix of either baggies over my regular bib shorts, or just the bib shorts by themselves, when I ride XC and trail. Wear the baggies over my bibs was ok, there were definitely times the shorts would slide around a bit or get caught on the saddle. These new Gore Alp-X 2 in 1's are definitely the solution to this.

I picked up my first pair early this summer after hearing others give positive feedback on them. They arrived and my first impression was that they felt quite light. I took them out for the first ride and immediately noticed the benefits. They were extremely comfortable, but didn't slide around and didn't catch the tip of my saddle. Despite the warm weather, they didn't feel too hot. The chamois felt good without any issues on the first few rides.

I subsequently took them with me on a few trips. While riding in Brown County, IN I did take a low speed tumble onto some rocks after losing my balance trying to hop up over some rocks. This is where I noticed the one weakness of the shorts. The baggie material is very light and the tradeoff is that it did get a small whole from where I fell on the rocks. No big deal - did impact the performance at all - but if you are someone who bails out and rolls or falls a lot, these might not be the best option.

Ultimately I liked them so much I bought a second pair. I took them both on a longer trip through Colorado, where I spent some long rides climbing Vail, riding the Government Trail from Snowmass to Aspen, and hitting a bunch of other single track. The shorts held up great and were always super comfortable.

Highly recommended!

Skip the spandex.... you ride a MTB

All the features of a high end technical bib short without looking like a roadie !

-Fantastic seat insert

-Super lightweight & breathable materials ( pic is from a 60 mile race in 90 degree weather and these kept me as cool as possible)

-Seamless integration between the upper bib and the baggy lowers and the riding specific cut keeps them snag free when transitioning in and out of the saddle.

Do yourself a favor and pick a pair of these up !

Skip the spandex.... you ride a MTB

I'd love to see this with front pockets as an option.

Hey Ryan these do have a small stash pocket in the front leg - plenty of room for a cliff shot or two and a cell phone etc.
