The BlackStrap Vista Base Layer Pant holds heat when temperatures drop far below freezing. A microfleece interior traps warmth against the skin while four-way stretch fabric moves with the body instead of restricting it. Flatlock seams lie flat to prevent chafing during long days layered under a shell. A soft-flex waistband and built-in fly round out a pant made for full days outside. What Our Gearhead(R) Experts Are Saying:"I wipe my goggles down with the Vista's fabric when I've left my cloth in the truck, and it's never left a scratch. The same fabric is soft enough that I stop noticing I have base layers on by my second lap."
