Coolflask Water Bottle Holder for 64oz Flask, Half Gallon Water Jug Accessories Carrying Pouch with Detachable Adjustable Padded Shoulder Strap - Carry, Protect and Insulate Flask for Bike / Outdoor

Fits a little tight however is strong and helps keep bottle cold

it fits perfectly with my 64 oz bottle Outerbanks, also with 64 oz Iron Infidel but it has a longer neck so it was more difficult but it fits anyway

The material and construction of the carrying pouch is very good. Neoprene at the top with nylon construction at the bottom. Looking at the material this should last quite a long time for ones that the pouch has an exact fit.Unfortunately the pouch is just a little too tall for Rtic's 64oz water jug, maybe by a half an inch. This half an inch means that the neoprene material actually covers the opening, making screwing the lid back on a huge hassle. The neoprene opening and the rest of the pouch is pretty tight on the jug, so moving them up or down is very difficult to do. If you move the pouch downward so the opening fits correctly, then too much material are bunched up at the bottom making the jug extremely unstable.This tight fit also means that bunching the material in the middle is not an option. The tight fit would be excellent if the material is cut correctly vertically. But for Rtic, you'll have to look elsewhere.

We’ve improvised with another strap. Not happy with quality for the strap should have lasted longer. -1 stars

It came in handy when hiking with two dogs. I was able to keep my hands free to walk the dogs on a leash.
