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 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.
I love, love, love these shorts. Coming up on a decade of mountain biking, I've been wearing "big brand' shorts that seem impossible to find in an XL (either they never make them or they're always sold out), so I'm, left feeling uncomfortable in shorts that are too long, too tight, and hit in all the wrong places. These, however, are so flattering and truly built for every size and shape. The first pair I ordered were too large (a miracle, i've never experience biking gear too large in my life), but I could tell they were going to be the ones so I quickly ordered two sizes down before I even had time to package and return the others. They fit great, they move and stretch with me, and start and stay comfortable throughout the ride. Thank you MFF <3
These shorts combine a more hiker fabric with a biker short silhouette. I recommend wearing chamois underneath because the fabric folds can create uncomfortable lines around the stomach area. It would be nice if there was some type of waist adjustment or stretchy fabric around the waist area to combat the wrinkles- maybe even getting rid of the need of a zipper all together. The length of the short is good and provides good coverage. I just think the short prioritizes fashion over functionality.
Ugh, I was so excited to try these out after reading reviews but wow, fit is so off for a brand that is centered around size inclusivity. Pros - nice details with premium materials and a locking button. Cool selection of colors. Cons - I'm 5'4 155 lbs. I'm curvy with thicker thighs and a small waist. These shorts gapped a lot at the waist and choked up my legs. I sat on my bike and backpedaled to see if I felt differently about the fit on bike only to find that it strangled my knees even more. Why is there no stretch? MTB clothes are supposed to be comfy.
