Less bulk. A whole lot of warmth. Made with Polartec® Power Dry® material, this silkweight undershirt wicks away moisture to keep you dry in wet, rainy, or damp climates. The Power Dry® fabric is highly breathable, with "touch points" on the interior of the fabric to wick the moisture to the outside, where it can evaporate easily. The Gen III level 1 undershirt is made with flat locked construction, from a material featuring Microban® anti-microbial properties to prevent odor. It is Level 1 of an extended/extreme cold weather clothing system that is highly effective.

Special features include double-stitched crewneck collar, hem, and sleeve cuffs, as well as thumb holes in the sleeves to ease the donning of upper layers, without the sleeves pulling up. Made in America, with pride.

Made by Milliken, nice quick-dry material, perfect for hikes or as a base layer. Thank you McGuire Army Navy, for offering this product at a great price.
