The Patagonia Stormfront 45L Roll-Top Backpack is perfect for those looking for a durable, 100% waterproof, no-nonsense backpack to accompany them on their wet outdoor adventures. The simple, streamlined construction ensures your valuables stay dry as a bone through heavy rain, splashing from boat spray, or while rolling around in the bottom of a canoe. A variety of attachments on the exterior of the pack allow wet gear to be separated from dry, and the durable fabric won’t easily be torn or punctured. Although it might not have all the bells and whistles, for the price, this is one of the most effective waterproof backpacks you can buy.
