Advanced base layer fabrics effectively pull perspiration from the body, accelerating moisture movement and evaporation for enhanced comfort during active sports.


Created using advanced specialty yarns and innovative knitting techniques, this new generation of stretch fabrics offers impressive levels of comfort and technical performance while keeping you dry and comfortable.

Therma-Loft Pro®

Designed to deliver high warmth-to-weight ratios, superior breathability and exceptional softness in a wide range of styles—from lightweight to velours to ultra-warm textured thermals.


Carefully selected yarns, state-of-the-art weaving and knitting processes and special finishing techniques provide varying levels of wind protection, while allowing moisture vapor to pass through.


Specialized lamination, bonding and shell constructions ensure these fabrics deliver the highest level of protection from the wind, rain and snow. Many fabrics in this series are created with added stretch.


Many of our PRO-SERIES fabrics are available in TERRA-PRO versions that contain recycled and renewable fibers, offering an eco-friendly choice for today’s environmentally- conscious companies and their customers.
