I have had a few of these, they have become a necessity on the water. With most of my Simms gear having Velcro, I can quickly attach this to my waders, jacket or packs so it's always with reach for my favorite flies.

When these are used in conjunction with the pile velcro on a Simms pack, the adhesive on the hook velcro on the fly box can fail. I finally superglued the velcro onto the fly box and it is now working better.
