It's all about the compound! DAKINE Posi Traction stays sticky and grippy in icy water and won't rub your knees raw in warm tropical water. The specially formulated EVA foam retains its specific density and 100% memory in any water temperature. Dakine uses only the best 3M PSA (Pressure Sensitive Adhesive) to insure that your pad will never peel off until you take it off. Only the best from DAKINE.
