Back in the 80's my buddy took the level 2 ski instrcutor and told us we need straps for proper wrist action on pole technique and in practise I agree with him but if you ski trees very much you might get your shoulder pulled out and also you gotta take them off everytime you ride the chair
i use this entirely new concept where i leave the straps on the pole and don't put my hand thru the loop
probably gona patenet it
no belt or a sizing chart either maaannnn !
