Warmth Made Possible Polartec Classic Micro Cap ®

Polartec® Classic Micro • Warmth without weight • Highly breathable • Dries quickly • Durable • Machine washable These hats, made with Polartec® Classic Micro with Comfort Stretch, replaced the World War II era black wool watch cap. They bring lightweight warmth and great breathability. The tight-knit microfiber construction is quick drying and non-irritating. The cap is fully fielded to the USMC and currently part of the U.S. Army’s Cothing Bag.

“The Microfleece Cap was rated significantly higher than the Watch Cap on almost all performance criteria and was the preferred choice to be worn.” –Excerpt from Executive Summary of U.S. Military User Evaluation of Microfleece Cap report, July 20, 2001, U.S. Army Natick Soldier and Biological Chemical Command, Natick, MA, page III

The developmental partnership between Polartec, LLC, PM Soldier and Natick is ensuring that our soldiers have the best available products to complete their mission.
