Leatt Adv 6.5 Hydradri GlovesTailored for smaller hands, the HydraDri 6. 5 gloves are constructed using the latest laminated waterproof design and HydraDri material, keeping your hands dry and protected. Reaflex gel protects the knuckles, and thermoplastic rubber (TPR) on the fingers has an elasticity that makes it ideal for protection. The soft MicronGrip palm provides full range of motion, and an all new laminated membrane construction improves the internal feel of the glove.
