What to know before buying

Listing details to confirm

The listing describes 40 oz capacity and an 18–40 oz bottle fit range. Confirm your bottle's dimensions and handle clearance, since ounce capacity alone does not establish fit. Magnetic hold depends on the surface and receives mixed customer feedback.

Frequently asked questions

Does it have room for a phone and keys?

The listing describes a front zippered pouch for a phone, keys and cards. The page lists two compartments and one pocket, so storage layout may be described inconsistently.
