Guide Gear® 10-oz. Poly-Fleece Underwear.

Bitter coldness is exactly why we developed this Guide Gear® Poly-Fleece Underwear. And our factory-direct pricing makes it the best value. In fact, we started with the U.S. Military's original E.C.W.C.S. Thermal Underwear and improved the fit and fabric for civilian-approved comfort.

This amazing 10-oz. polyester fabric insulates incredibly AND it's hydrophobic ("water hating") to suck moisture off your skin when you work up a sweat. Even better, this fabric does NOT retain odor. Brushed-fleece finish inside.

  • Crewneck has cuffs with stretch Lycra®
  • Machine wash / dry. Imported.

State Size, as available in the Shopping Cart. 

Please Note: This item may be Kenyon or Guide Gear brand. Sorry, no choice.
