This Bottle Sling is the simple solution to transporting your H20 hands-free. That way you can eat snacks, skip rocks, or indulge your dog in a riveting round of fetch. Mount it to the HitchPoint(TM) Grid on any HopperA(R) Soft Cooler (or the Camino(TM) Carryall Bag). But if you&';re lookin&'; to hike light, clip on the removable carrying strap, sling it over your shoulder, and enjoy the journey up to that gotta-see-it viewpoint.
