What do you mean? Geeky how? Like only nerds would use it? I'm all for constructive criticism, I'm also a geek, so there you go. Thanks for looking. Actually the geekyness flaw you mentioned can be overcome by the broad patent claims. These cover many variations on the central theme of the bottle sling. Not only different fabrics, patterns and colors, but designs too. How's that for geeky?
