The YETI Flask is a 7-ounce flask for carrying along a nip on any adventure. Overbuilt and leakproof, the single-wall 18/8 stainless steel will hold up to the outdoors, a drop on the sidewalk, and still hold onto the drink you've stashed inside. An included funnel makes it easy to fill, while the curved shape slips easily into a pocket. A stealthy bevvy is never far from reach and ready to be shared by the fire.
