I am looking at a larger Fanny pack to wear in front when backpacking. These 2 are 3/3.5 liter. Both of these allow use by belt or by strapping to chest. But Zpacks provides those straps. Any one have experience with either? Are they mostly waterproof? or will phones etc still need to be in a ziplock? Anything you liked or disliked about either one? I like the idea of DCF to keep things dry from rain and sweat.
