Ti2 Sentinel

Have some stuff you need kept safe — and we mean really, really safe? Place it inside a Ti2 Sentinel ($25-$200). Available in small, medium, and large versions with differing interior diameters, these titanium tubes are completely waterproof and corrosion resistant, can easily be hooked to rings, clips, or lanyards, and offer a three-piece design to ensure you can get everything out of them when the time comes. Great for caching survival tools, cash, and medicine, and also serve as stylish pen, key, or flash drive storage.
