The Perdix is best worn with 2 independent loops of the surgical tubing that came with it. Get it sized right for your wrist+wetsuit and then make 3 very tight knots through the holes at the edges for each of the 4 end points and stuff the ends through the long slits the strap would go through. Goes on and off very easily but sits securely, no clips or clasps or buckles, nothing sticking out anywhere.
