A thumb loop helps putting them on and taking them off. The anatomically perfect fit and breathable soft inner fabric with wide surface area allow the strap to be held firmly yet lightly. The Frame Strap Shark is made from one piece and encloses the hand all the way round. Fabrics do not overlap annoyingly, thus preventing blisters or pressure sores. The width is infinitely adjustable with Velcro. Direct connection to the grip ensures that every impulse is transmitted to the pole with no loss of power.
