Men's Foundation Short - Men's Mountain Bike Chamois | 7mesh

Products that blend performance fabrics with highly articulated patterns to create a close-fit that feels like an extension of your body. Skin Fit apparel improves aerodynamics, moisture management and thermal efficiency.

Skin Fit

The Foundation Short is the best padded undershort I've found in my over 30 years of riding. I've used may different brands...and they're good...but there is always some small issue with them riding up, binding in the wrong area, the elastic pinching, the pad being too big, the foam not dense enough, etc. I haven't been able to find anything wrong with the Foundation Short. When riding, I actually forget it is there because it is so comfortable. I've never had that with any other chamois short.

Best Chamois I've Found

These are so comfortable it's actually really quite something. Great cut, still going strong after several years. Have bought the bib as well...!

Fabulous shorts

I had the previous generation of these and find the updated model to be a big upgrade in terms of comfort, cushioning and use over longer rides. The one big call out is the sizing, I'm generally a medium but would go with a small next time, the online size guide is accurate

Excellent comfort on long rides

Solid so far (a few months of summer riding). I find that the pad part is a lot bigger then my previous 7mesh pair, and somehow the new ones feel like they more moist then the previous ones when ever i wear them. Other than that I forget I have them on and can ride all day no issue. Solid.

I was between medium and large according to the size chart, ordered large, and they're as expected. Quality is excellent, I'm happy with the chamois and would order again.

Liner padding is thin but comfortable, very "airy" feel due to materials used. I will probably try the next size up next time as they feel a little too tight.

Great trail short. A little lightweight for my taste for gravel or road and perfect for trail riding where the saddle is a little less of a factor. This also means the pad is a bit lighter and easier to wear after the ride. My GF calls these "lingerie for men" - the mesh sides are well ventilated and super comfortable and apparently pretty damn good looking. Worth every penny. Thanks, 7mesh!

Bought these for trail riding. They are very comfortable for wearing under a mountain bike pant or shorts and do not interfere with knee pads. They are cool in summer, but you will need an additional warmth layer overtop when cold-weather mountain biking. Bought the medium, but I am sized more between medium and large as my hips are 105 cm and thighs are 55 cm. I would buy these again.

Bought these for trail riding.

Easy to get back in the saddle the next day after a long ride. No pain, no swelling no problems like that anymore. Will not buy any other branded pair of under-shorts now that I’ve tried these. How can you put a price on pain-free. And they look good around the campfire too.

Easy to get back in

The Foundation Shorts are the finest undershort I've ever seen. First off, the chamois is a legitimate top quality long distance/ultra distance riding chamois, not the crap chamois used in every other undershort I've seen. The mesh sides make for cool riding and the real innovation of having a cutaway in the front of the chamois means your man parts don't get crushed or chafed like nearly every other short. Instead your stuff is cradled is super soft, stretchy lycra! This makes for a comfort level unlike any I've experienced. Especially on ultra distances, the chances for crushage and chafing of your junk are gone. Pure bliss. I suggest 7Mesh use the same approach for all their bibs and shorts. Sizing is interesting. I wear a medium in nearly every other brand of shorts, but the 7mesh recommendation is for a small, which I got. It's fine, but I think I might be between a small and a medium in their system. However, the sheer comfort of the Foundation Short means you can get away with slight deviations on size. This is a holy grail cycling short for me and while expensive, it's worth every cent.
