OPR are my go to pants!
These are my go to pant year round! In the Maine winter I wear them with a lightweight Stio merino base layer. The slim cuffs are great for sliding into tall boots. The fabric is comfortable and durable. The hip phone pocket works great. My only suggestion is to improve the waist adjustment hooks which are difficult to engage or adjust once the pant is on. I removed them since the fit is perfect for me without them.
OPR Pants
Have now worn mine for a gravel bike ride on a day that started in the 20’s and made it to the 50’s and a mountain hike in the 40’s. I love them. The fit is sufficiently slim such that there isnt a lot of fabric flapping around on the bike, but the stretch makes them comfortable for both riding and hiking. I am 5”10”/ 180 lbs and bought the 35R. Had them hemmed to take out about 2 inches of inseam to make room for hiking boots. Would definitely recommend for any cool-ish outdoor activity.
Fantastic and well designed
Great pants that are functional and stylish. Can dress them up or down. I love the back pockets being shifted over to the side which I personally find more comfortable even for just daily use not to mention biking. Fitted just enough around the ankle to look good and tuck into my muk luks easily.
Favorite MTB pants
I have a couple of pairs of Zoic Edge and one of Specialized MTB pants. I like the design/style of the former (normal jean-style pockets) and the fabric weight of the latter (Zoics very thin), and the Stio OPR combines the best of both, so they are my favorites.
Great for riding
Love the fit and cut. Went with the 32 based on size chart and they were perfect. Like the adjustments at the back to dial them in. Good stretch as well for on the bike.
Great pants
Light, stylish and currently the most comfortable pair of pants I own - what is not to love. :) I also like how quick drying they are.
Very happy with these
These are nice. Can wear them in warmer weather than I thought. I will likely wear them hiking and casual. Now have 2pairs.
