Dri-Release® Wool

This intimate blend of 12% Merino wool and 88% polyester feels similar to cotton and keeps wearers comfortable, dry and odor free, as the permanent FreshGuard® system prevents odor and bacteria from developing. Dri-Release® Wool has been proven to dry faster than 100% cotton, 100% polyester and even 100% merino wool. Additionally, in standardized tests, Dri-Release® Wool fabrics were found to be 29% warmer than merino wool fabrics of equivalent weight. Outdoor Research uses Dri-Release® Wool in the construction of select winter headwear.
