PolarMax Phase 3 Super Midweight Base Layer Long underwear pants for men are made of 90% Acclimate Dry Polyester and 10% Spandex. These pants offer an athletic fit; they're great for action sports.
These pants won't shrink, pill, or fade. They are machine washable - just toss in the wash and dry.
Acclimate Dry performance fabric stretches more efficiently, allowing for high-energy activity while reducing muscle fatigue. XGO's Phase 3 have been engineered and field tested to work in comfortable conjunction with ballistic protection of all varieties in all climates.
XGO's acclimate dry fabrics wick moisture vertically at a rate of 3" in 3 minutes and 90% of the wicking properties are retained after 50 washings, as designed by U.S. Military standards.
These Phase 3 pants are protected and enhanced by Scent Prevent and anti-microbial infused engineered gussets.
