This moisture wicking material is used on Burton layering pieces to help keep the wearer cool and dry during excessive activity. Micro fibers pull water away from the skin to the outer layer of the fabric, where it can easily evaporate. Stretch qualities in the materials used means Ultrawick™ garments move comfortably with your body’s nature motions, eliminating bunching and binding. Given Burton's DRYRIDE seal of approval, these fabrics are perfect for base and next-to-skin layering.
