those velcro straps seem to be worthless
When I first got this, I tried using the velcro straps like in the diagram. The velcro instantly created a fuzzy mess on the sleeve itself. I used my sewing ripping tool to remove the velcro strap and just put the sleeve on every evening. It's fine and somewhat helpful, but I still have a velcro base patch on the front. Strange design.
