Superior moisture wicking is critical for comfort. It decreases humidity against the skin to keep your patients feeling drier and cooler. Superior moisture wicking is the combination of 2 things: spread and speed 1. Spread of moisture. The larger the area the moisture covers, the faster it can evaporate. 2. The speed the moisture spreads to that maximum area means it can evaporate faster. Moisture is less likely to get trapped against the skin to keep your patients cooler and drier.
