Bottleskinn by BBBYO Neoprene Insulated Carry Cover - Multiple sizes. Fits BBBYO, S'well, Minimal, Mira, Water Vault, Corkcicle, Hydroflask and Klean Kanteen steel bottles

It fits my 17 oz bottle all the way to the top. Love the little side handles so I can carry with no strap. The strap is extra long. Big plus. We plan to carry them to the grand canyon. So the extra long adjustable strap is going to be perfect. The cover itself will allow a firm grip on the bottle. Very pleased
