Will it fit a 40 oz tumbler?

It is sized for cups about 95-100mm in diameter, which covers most 30-40 oz insulated tumblers. Measure your cup's body width before buying; a much narrower cup will sit loose.

Is the strap long enough to wear crossbody?

The strap adjusts from about 64.7mm to 1180mm, so it works as a shoulder or crossbody carry for most adults. The swivel lobster clasps let you remove it.

Does it keep drinks cold?

No. It is a PU leather carrier with no insulation, so it adds no chill retention. Its job is carrying and protecting the cup.

PU leather should be wiped with a damp cloth rather than machine washed. Soaking or repeated water exposure can break down the coating.

One cup holder with its adjustable strap. The tumbler itself is not included.

How does it compare with a neoprene tumbler sleeve?

It offers a shoulder strap, a pocket and metal clasps that most neoprene sleeves lack. Neoprene is more water-resistant and stretchy, while PU leather looks dressier but needs more care.
