As always, we put fit first and this product was thoughtfully developed to perform for every shape. Offered in sizes 24 through 38.
This slide-locking snap closure will keep you buttoned up, even when you're letting loose.
Our contoured hem means you won't have excess fabric bunching behind the knee, and the slim fit through the leg will keep you looking sleek.
Our 4-way mechanical stretch gives you maximum flexibility. This short will truly keep up with you where ever you are headed!
For cycling bibs and shorts, the HIP MEASUREMENT is the most crucial factor. Measure around the WIDEST POINT of the hips/bum. If you are between sizes or petite (5'3" or under), we recommend SIZING DOWN for a compressive fit. A snug fit is crucial to performance. Check out our FIT GUIDE for more detailed instructions, or pop your measurements into the fit calculator above for a personalized recommendation! (Please note, the fit guide requires chest, waist and hip measurements.)
I bought these and, I’ll admit, a pair of Assos liners to go with them because I am a hard-core Assos fan. These are beautiful! I love the long length - same as regular bike shorts. Very comfortable and no fear of ripping or gaping.
Pretty true to size, comfortable fabric which is light and keeps your cool
Dry's quickly and works well with the Foundation Liner short as well as other kicks
Comfortable and stylish and move and stretch with you.
I love this short (Longer length) - it fits perfectly, has just the right amount of stretch, washes GREAT and I received a number of compliments on the short. I now own it in both the olive/khaki color and in black. I wore both a machines padded short (Not the bib) as well as an ASSOS short underneath it and it worked great with both - covered 82km with it with no issues and the next dat 66km (Obviously with a wash in between) - and no issues either. Would recommend it for sure.
I recently started mountain biking and was appalled that the only mountain bike shorts were baggy cargo pants that looked like they were designed for teenage boys. Through some precision ads targeting on Instagram, I can across an awesome ad for MFF's mountain bike gear. These shorts were exactly what I was looking for! Form fitting (but not too tight), comfortable and stylish. I read from the comments that the sizes tend to run large so I ordered a size 26 and they fit really well (I'm 5'8" and about 133 lb, usually wear a size 28 in pants), so would definitely recommend sizing down from your usual pants size. I'll definitely be buying more MTB gear from MFF!
I usually mountain bike in spandex so trying a baggy short was new for me! These shorts are the perfect combo of fitting snug and looking streamlined while not being full spandex! They’re really good quality and the stretch is great. I also like wearing them on the reg when not riding! The only thing is that I didn’t buy the liner shorts, trying to save some money, and I wore them with regular bibs underneath. It was really hot so I wouldn’t recommend it for summer. Probably best to get the liner shorts.
