Customer Reviews

Comments: I love the feel of these pants; however, they run too short for my legs. They are an awkward length for me, which was a disappointment.
From: Kristin, MA, USA. January 10th 2015

Comments: I would live in these pants if I could! Super comfy and flattering, have worn them for warm up/cool down during cooler weather races and on longer training runs when temps dip down into the 35 degree range (any warmer and I usually wear tights). Also just like having them on for lounging after runs--they are so soft. I am 5'7, 120 lbs. and bought a size medium just to make sure the length was right; I like a 31 inch inseam. I have to tighten them in the waist with the adjustable tie but other than that they are just fine.

Comments: Love these pants! I actually enjoy running in pants year round. I was looking for something light and comfortable to wear during the warmer months. These are so soft (similar to t-shirt material), lightweight, and flexible. There's no compression feeling with these pants. Also great for wearing while doing yoga, walking, casual activities, etc. Love the little pocket too. Had to buy myself a second pair.
