  • Avra™ keeps you comfortable with superior wicking speed and exceptional dry times - up to 50% faster than fabrics of similar weight, construction and composition. Due to their size and unique shape, Avra fibers are significantly more flexible than standard polyester. This creates fabrics with a distinctly silky feel that keeps you drier and more comfortable than ever before using 100% post-consumer recycled PET. The flat, ribbon-like shape of the smaller fibers provides performance advantages like faster wicking speeds, faster dry times, and a cool-to-the-touch sensation you have to feel to believe.
