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™ Grid on any Hopper® Soft Cooler (or the Camino™ 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. Small sized to fit the 18 oz Rambler® Bottle. Rambler Bottle sold separately.
