Customer Reviews

Comments: Best shorts I own! Fit is amazing, liner is great, and pockets are sweet. They are expensive but extremely high quality and worth every penny. These are my go to race and marathon shorts. I have several pairs of Brooks, Pearl Izumi, and InSport. I log 50-65 mi week during peak season.

Comments: I've been running in these shorts for almost two weeks and they've been great. Fabric has a really nice feel and at size 34 waist the M fit well. I've experienced no bunching and they've stayed comfortable throughout long runs. The side holster pockets along with the rear zip pocket are perfectly positioned. I can fit my iPhone in the huge rear zip pocket and can't even feel it when I run. These shorts are expensive but I'd say it's worth it and I'll be buying more PI gear in the near future.

Comments: I think PI needs to stick to cycling. They don't understand the running short. I'm a 29 waist. Small guy. So I bought the sm. size. This seam that has the stretch material connected in the back and sides to the short does not work with the short material. The material is conforming yet the rest of the short is loose. Causes way too much bunching and gathering on a run. Not good. And cost is too high.
