What really sets the Seventy2 apart is the bag the tools are packaged in—and the way they're organized. Made from 60-denier tarpaulin, the 30-liter roll-top pack is completely waterproof and should remain so through plenty of abrasion and manhandling. That doesn’t just mean it’ll keep all the gear inside dry: it also turns it into something of a multi-tool. Need to haul a bunch of water? Empty the pack and dunk it in a lake. Need to get in that lake? The pack doubles as a flotation device.
