Omni-Wick is the ultimate moisture-management technology for the outdoors. Its superior wicking properties move moisture away from the body and enable perspiration to evaporate quickly. During physical activity, increased body temperature causes perspiration (you know, sweat). Normally this results in damp, clammy, and uncomfortable clothing (not to mention unattractive). With Omni- Wick clothing, moisture is quickly wicked up into the fabric, and away from the wearer's skin. The moisture spreads out across the surface of the fabric where it quickly evaporates. This wicking/evaporation process keeps the wearer cool and the clothing dry. You stay dry, which helps regulate temperature, prevent chafing and keep you comfortable all day. Work up a sweat without getting all wet.
