Review on Water-Resistant Nylon Drawstring Backpack For Gym, Shopping, Sports, And Yoga - WANDF Cinch String Bag Sackpack (Black) by Casey Murphy

It's nice that the straps rely on knots rather than seams, so if it falls out you can just tie a bigger better knot instead of having to sew it back up. Mine hasn't fallen apart yet though. I love all the pockets and it seems pretty sturdy. A little stiff in the drawstring but works for my purposes. Haven't taken it on a long hike or anything yet so can't speak for the strings digging into my shoulders, but they're thicker than regular strings-- more like rope, so that's at least better. They do tend to fall off my shoulders a bit, but I just use a carabiner to hold the ropes together in front of my chest. Haven't really tried it in the rain yet but it seems like it would be fairly water-resistant.
