Customer Reviews

Comments: I was looking to get a new pair of pants to use as warm-ups and for cold-weather running. Basically wanted to update from my "swishy" wind-pant style so I tried these. Pros: Very comfortable. Cons: Legs do not taper or have elastic at the ankle so if the pants are any bit too long, they will fall over your heel and get stepped on when you run. The zipper quality seems poor (one of my pocket zippers broke after one use). Overall I would not recommend, the comfort does not outweigh the design flaws. Run 30 miles a week, 3:24 marathon, 1:31 half marathon

Comments: Probably the most comfortable pair of running pants. They almost feel like lounge pants and I do not want to get out of them. Got them on a great sale price and they work great.
