The moisture can transfer from one side to another side only in one way (from the inner side to outer side only),and wicking.

GOCOOL, a hi-tech functional fabric with wicking ,quick dry and protection, originates from material-modification, special structure design and finishing. It can make it rapidly absorb sweat and moisture from skin surface, transport to fabric out-surface, and then evaporate, and also prevent moisture transfer to inner of fabric from natural water. It can always keep the dry ,cool and health condition between GOCOOL and skin in any cases.
