The Wilson WTA20RF151275SS A2000 features the custom fit system which ensures an easy break in and snug fit. The Dri-Lex technology is an ultra-breathable wrist lining that transfers moisture from the skin, keeping the hand cool and dry. The Dual Welting is done twice on each finger to provide the most durable pocket and long lasting break in. The Superskin back repels moisture and reduces the overall weight of the glove. This feature is unquestionably the only legitimate alternative to leather when making a lightweight glove without sacrificing durability. Superskin is two times stronger than leather and half the weight.
