SINOTOP Dry Bag Waterproof Backpack 35L Roll Top Sack Keep Gear Dry for Floating Kayaking Boating Camping Canoeing Rafting Hiking Skiing

UPDATE; The seller refunded my purchase. It could be a great bag if the shoulder strap attachment design was reliable. For light use, it is a great bag especially for the price, just not built for any real abuse.ORIGINAL REVIEW; Nice design for a small waterproof back pack. Don’t expect to use this reliably for any real adventures. The bag remained waterproof for the time I used it, however the straps did not. On the first trip, three days of backpacking, the side pouch ripped. On the second trip, 5 day backpacking, all of the straps ripped off and the bag became unusable as a backpack. I would advise investing in a stronger bag if you are planning to use it in the backcountry.
