40 oz Bottle Sling

Sling your bottle for hands-free hydration on the go! Our super-durable Premium Sling protects your favorite 40oz ThermoFlask bottle from dings and gives you a few extras to level up your adventure: the short, easy-grip side strap and longer, fully adjustable/removable shoulder strap make it easy to grab, hang, sling over your shoulder, wear cross-body, or clip to your cooler. The rugged nylon construction snugs your bottle on the inside and holds its shape on the outside, so you can set it down without bottle wobble. And the stretchy pocket is great for stashing all the things when you want to leave your backpack at home.
