Phantom Aquatics Walrus 25 Premium Waterproof Backpack Dry Bag - Yellow | Waterproof Gear for Kayaking, Boating, Camping & Outdoor Adventures

Got this for daily rides (17 miles x 2) in rainy conditions. Putting computer, phone and clothes through the distance: they stay dry (I don't). Comfort is good, the straps and belts are padded and hold tight while in motion. It takes slightly more time to close it and open it as you need to roll the top and attach it on both ends. More durable and sealed than using a zipper. There is one inside pocket which is tiny and could be twice the size.
