These are knee pads you can wear all day. The straps are soft to the touch, easily flex as you move and don't pinch or bind behind your knees when crouching.
The pads have soft layers of memory foam that conform to the shape of your knees and a thick core of dense EVA foam to prevent debris or surface irregularities from creating pressure points. The outer covering is nylon with a neoprene lining for water resistance. Hook-and-loop fasteners make strap adjustments easy.
The only downside to these knee pads is that the hook portion of the strap can sometimes snag and fray the nylon covering. While this may detract from their appearance over time, it won’t diminish their comfort or performance.
