You won't find anything with more velcro surface area. We know velcro, baby. Its actually kind of a problem. There's velcro everywhere. My stepchildren think I own a "velcro company". Maybe I do.
We also know our customers respect quality where it counts. That's why we used heavy duty metal Quick Release Buckles. They're the safest, most finely crafted, and strongest load-bearing buckles available anywhere. Hell, the buckles alone weigh a 1/4 pound and can easily double as a modified flail-like weapon.
These fanny packs can carry your stuff, keep your hands free, display your patches, double as a close combat weapon, attract mates, and establish dominance.
