The Hookgrip knee sleeves made with 35% rubber, 55% nylon and 10% spandex. These provide warmth and a small amount of support, they are not as compressive as thicker wraps and knee sleeves. Kristin wears these on the Snatch in competition.
The price here is for two knee sleeves. They are not sold individually.
There are five sizes: XS, S, M, L and XL. Size recommendations are approximate because these are stretchy knee sleeves and sizing depends a lot on your personal preference for tightness. Kristin wears size Small.
