The thumb strap supports your pushing and the return movement. The anatomically perfected style and breathable soft inner material with a wide contact area let the strap fit securely and smoothly in your hand.

The Frame Strap Shark is made from a single piece and encompasses the hand 360 degrees. There is no overlapping material, which prevents blisters and bruises. 

The width can be adjusted freely using the fastener, while the direct contact with the grip ensures that all the momentum is transferred to the pole without a loss of energy.

 With the Trigger Shark 2.0 device, you can hook and unhook the strap to and from the pole handle lightning fast.
