These are made of a premium quality, soft and washable cowhide leather. The Hyprene back is breathable. Neoprene covers the knuckles for protection and comfort--they won't feel tight when you close your hand. The palm is sculpted for comfort and reinforced for toughness; neoprene cuff and Velcro wrist closure for custom fit. We've replaced the Bionic Gloves with these...we think they're longer wearing, as comfortable, and much more reasonably priced. Available in Purple, Gold, Red or Green. Womens sizes small, medium and large. Mens sizes medium, large and extra large.
