I like the pants. Got 2 pair, same inseam size and one is 2 inches longer. Except for the difference in length, the pants fit fine and work well. But somebody there ain’t too good at math.
This will be my MTB pants to pedal in
Seriously stretchy material and the shorter 9" inseam makes it the perfect pants to pedal in, does not catch the knee when you don't want to. It has enough room to comfortably wear chamois underneath. I feel it runs just SLIGHTLY on the larger side but the waist band allows for adjustments to perfect the fit. Nicely surprised with the attention to detail, quality zip / buttons and excellent finish.
Love these shorts. Came back
Love these shorts. Came back to buy a second pair. The shorter inseam is great for me as only 5’8”. The adjustable waist is a nice feature as is the offset zippered wallet pocket (it gets your wallet out from under your bum. I wear them off the bike as much as on and they are comfortable for hiking and other non-bike stuff
Love the shorter version
I bought these because I already have the longer version. I was stoked when they came out with the shorter more everyday wear version versus the more biking specific longer. I wear these for everyday use or running even. I wish they were like a half inch longer. Still great shorts.
Sweet short, I wear them everywhere
These are great. Fabric is perfect thickness and stretches nicely. I find myself wearing them everywhere - way more than just when I’m riding. Glad I ordered the shorter ones - I would likely only use them for riding if they were longer.
2nd pair
I have 2 pairs. I bought the second 9” inseam based on my love of my OG 11” inseam shorts. I simply prefer the originals longer shorts cut, fit and design better. They are great shorts and try them and see if they work for you.
Good for bikepacking
I really like these shorts. First 3 say bikepacking trip and they held up well. I like the pocket positioning and the waist adjustment mechanism. Very comfortable while riding. Would go with the longer shorts next time.
Bought these for trail rides. Ideal for summer heat with a good chamois underneath. Then wear for post ride meal etc. if not too dusty, etc. Zippered pockets great for valuables, keys, etc. Would buy again for sure.
Versatile Shorts!
My favorite shorts of all time, and I love the shorter version now having bought the 11 inch in the past. I’d wear them every day if I could!
I finally found what I was looking for
My favorite mountain biking shirt (and I have lots). Great stretchy material, but most importantly, the pockets are all in the right places
