VSSL's space-saving genius, in an even smaller package. This virtually indestructible, military-grade aluminum cylinder has a waterproof Bluetooth speaker in its end cap, capable of pumping out your favorite playlist for up to five hours. The rest of the body houses two empty aluminum tins to fill with any outdoor essentials you need—think fishing line, flies, that kind of thing. The cherry on top? The whole package clips easily to your bag, thanks to a carabiner in the magnetically sealed waterproof cap.
