These M48 Kommando survival flasks are great to carry in a hiking or camping pack. They flatten, fold and roll when empty. A funnel is included for spill-free filling and a screw-on pop cap ensures it won’t leak when not in use. A caribiner clip is also included to clip your flask on a pack, or to be clipped under clothing to sneak a drink in where they aren’t allowed. Package includes: 1 28-oz. flask, 2 16-oz. flasks, funnel and caribiner. Each M48 survival flask has a water hydration survival guide on the back. Don’t get caught with dehydration!
