Overpriced - Armageddon Gear Squishy Rear Bag

There’s too much hype around this for what it is and it is frankly overpriced.
The magic of this bag comes from the stretchy fabric around it. The filler seems to be about the size and consistency of silica desiccant beads.

I feel like I can accomplish the same with a Lycra sock and a liter or two of beads…

I wish there was a way to adjust filler and that the carrying strap was adjustable to tighten it around your gripping hand.
