ts not often that such a simple but effective product can make fishing so much more comfortable. The angler hangs his fly net in one of the clips and the other clip goes into the eye on the back of his fly vest. When he needs the net, all he has to do is pull on it and hes ready for action. The elastic is just to make sure that the cant lose the net (for instance if he has to walk through bushes or if he is standing in deep, running water).
