Is this site buggy for anyone else? Before I could read the main content I had a popover asking (I think) for a Facebook Like (gross) and before I could fully read it/dismiss it it was replaced with a different popover showing Seinfeld and a coupon code. Then I gave up and came here to be snarky.
These are a little more graceful looking than Shirt Stirrups. (lol).
Not too complicated of an idea. Looks like it provides a little bump on your shirt to provide residence from your belt to moving down or your shirt moving up.
Looks like a good convenient idea, but he's pretty clearly going easy on it and not lifting his arm/shoulders above 90° when demoing it. No way that army guy should have let those jumping jacks pass.
Still looks to adequately solve the problem, if not perfectly.
