Hyperflex Pro Series gloves are an extremely warm sealed seam glove with a fleece lining. Waterproof glued and blind-stitched seams are coated with a fusion weld. The palm is coated for maximum grip. The pre-curved shape ergonomically fits your hand causing less fatigue. Easily, one of the warmest gloves on the market. The AQ6 Thermal fleece is a soft, thin fibrous fabric which internally lines 90% of the suit which increases warmth, comfort, and has quick dry properties while also allowing for maximum stretch.
