Review on 🧴 Kvvdi 3 Pack 16 oz - 21 oz Neoprene Water Bottle Sleeve 16.9oz Portable Bottle Cooler Cover Holder Strap for Outdoor Adventures by Sam Duppa

Works great, keeps water bottles from fogging. Comes in three different colors: light blue, pink and black to red reversible. A cleaning brush was included, what for? I'm not sure because they are machine washable. Their top clasp allows them to be attached to a belt loop, backpack, etc., but if you have a refillable water bottle with a taller cap tucked up your sleeve, it may be difficult to attach to your bag, etc., and you maybe you only want to take a carabiner. All in all I think it's a good deal.
