Description The Knee Cushion, or Knushion, is essential for all day comfort. Some people choose knee pads, while others like a cushion. Either way works, but the Knushion is the maximum comfort option. Knee pads may be a little more robust in certain circumstances, but not quite as comfortable. Grit chose a super light, yet durable foam for the Knushion to make sure you stay comfortable all day long. Simply hook it to the tree and stay comfy for your whole hunt.
