I love these tights! I wear them as a base layer when mountaineering. I also use them under my TNF nylon hiking pants for float tubing. (I have breatheable waders so I need some insulation.) They are extremely comfy and do an AWESOME job of wicking away moisture. Even alone they will take the bite out of pretty cold air. EXCELLENT!!

Customer Service

Not much. Just a question and they responded pretty quickly. I have heard great stuff about TNF though.
