I bought a butterfly II last fall. Great saddle I like it. But my leg straps and waist straps keep loosening themselves. I find myself tightening them in a tree quite often and its just getting old. I thought they would eventually just break in, I've spent alot of time in it and they haven't yet. Anyone have any solutions to this. I thought about having them sewn together behind the buckles but I would like still like to be able to adjust it for the winter.
