Review on 🎒 IDRYBAG 30L/40L Waterproof Dry Backpack Dry Sack: Ultimate Outdoor Gear for Water Sports, Kayaking, Boating, Rafting, and More! by Jacob Kuntz

Exactly what I was looking for. It's totally waterproof so you can literally throw it in the lake and keep your stuff dry. It's also pretty durable. I bought it for caving which involves a lot of mud and squeezing between tight rocky spots so the bag really took a beating and was very easy to clean afterwards. I've also used it for climbing gear (I attach my helmet to the convertible top) and for getting around town when it's raining. The inner pocket is also really handy for giving me quick access to things like my keys and roomy enough to easily store other essentials like a first aid kit and flashlight. I am very happy with this bag!
