I got this on sale, I initially thought I'd return it, but decided to give it a chance because it was affordable. I'm slowly converting to the feed bag lifestyle. Though, I don't get why it has to be called a feed bag. I strapped it onto the seat belt 5 bar webbing of the folsom 2.0 shorts to have a handy pedestrian water bottle holder. I've rocked it on the stem of multiple bicycles, carrying extra items. The big elastic, exterior, pockets really differentiate this product from other similar concepts. It can hold an enormous amount of weirdly shaped, small, items. I combine it with a hip pack as well. It actually works great with competitor hip bags as well as with something like the Cardiel Shank. This bag can hold a 1 liter evian bottle or a 12oz disposable water bottle. More importantly, it fits lots of re-usable bottle options like Canteen, Nalgene or Camelbak. I think it would make a great pocket to stash sunglasses after the sun sets, but I won' t really be able to pragmatically test that until fall when the days get shorter.
