I saw these Seal Line Boundary Packs at Uncrate and instantly fell in love with the company’s line of waterproof/watertight bags and packs. All of their bags are rated for heavy outdoor use (think hiking, camping, rough water sports, etc.) and the Boundary Packs are made from 30-ounce scrim-reinforced vinyl bottom with a 19-ounce scrim-reinforced vinyl body. Not sure what that means? Just know that the bags won’t break very easily. Plus, their roll-top enclosures make the bags watertight enough to prevent them from sinking if you drop them overboard.

The best part is that the bags are reasonably priced at $70 to $90, depending on the size you get.

Below are the Wide Mouth Duffle bags which also have a roll-top enclosure. One word: awesome!
