Generic Caveat: As with all Fox products, it's built tough, in configurations like the highest-level mil-spec bags, but on a budget. Due to the budget angle, they really can't be the "best" in terms of toughness. I don't mind. I love the features and designs and I'm not actually dragging my wounded buddies by the straps away from combat. They're great for outdoor and travel duty, with elite features at half the price, is my summary. It doesn't hurt to have a travel sewing kit.
