What to know before buying

Listing details to confirm

The listing gives the capacity as 25 oz in the title but as "1.6 pounds" in the capacity field. Pounds measure weight rather than liquid volume, so confirm the intended usable volume before buying. The claimed cold-retention time is a listing statement, not an independent measurement.

Who is it for?

A good fit for

People who want a reusable stainless steel bottle for protein shakes, drink mixing, gym sessions or water.
Buyers who value a lockable flip cap, dishwasher-care listing and cold-retention claim.

Less suited to

Anyone who needs a leakproof guarantee, since customer feedback includes both leak-free experiences and seal concerns.
Buyers who require a verified liquid capacity without checking the conflicting capacity details.

Frequently asked questions

How much does the listing say this bottle holds?

The title identifies it as 25 oz, but the capacity field says "1.6 pounds." Those details conflict, so verify the usable liquid capacity with the selected listing before purchase.

How long does it claim to keep drinks cold?

The product description claims drinks stay cold for up to 24 hours. This is a manufacturer listing claim, not an independently measured result.

Can it be washed in a dishwasher?

The listed care instruction says Dishwasher Safe.

Does the lid prevent leaks?

The listing describes a lockable flip cap, but customer feedback is mixed about leakage and the seal. A lock should not be taken as a leakproof guarantee.
