    Perfect gym bag!

    My new favorite gym bag. Had searched for a couple months for a new bag, the best I found was WolfPak, but their bags are inferior quality and overpriced. Then I found the SACK bag. Not only is the color/pattern much better, but it's a great build quality. Has just the right amount of pockets, and I love the MOLLE patches for funny patches. Great bag, I would definitely buy again but I think this bag will last me quite a while!

    Only issue

    Everything feels great on it. The only thing I would change is the interior liner is black and when searching for things in a black interior it is a lot harder to locate as opposed to a lighter (white or bright) interior.
