Everyone who runs, walks, bikes or partakes any sort of outdoor workout knows the struggle -- where to stash the housekey that isn't intrusive and/or uncomfortable? After years of stowing it in running short pockets, socks, and wherever else it shoudln't be, gokey wristbands solves it in a single wrap of sweat-proof silicone. A design so smooth, the key itself becomes the locking mechanism. And a fit so secure that the "go" logo on top serves as a release button. Though they're not in production yet, this is one Kickstarter project worth a preorder pledge.
