I bought one pair. I liked them so much I bought a second pair two weeks later. I can't vouch yet for their durability.

Great customer service

Ordered 2 pairs of grid fleece bottoms and only received 1. Sent an email and they got back to me next day! I received my other pair a week later. Thank you for great customer service and great products.
