YETI Rambler Cup Cap accessory — 5 oz stainless-steel detachable cup, No Sweat finish

The YETI Cup Cap is a detachable 5-ounce stainless-steel cup that snaps onto Rambler Bottles to give you a convenient, durable drinking cup anywhere you go.

Designed to pair with YETI Rambler Bottles, the Cup Cap keeps a ready-to-use cup attached to your bottle so you never need to set the bottle down to pour or sip. It combines kitchen-grade 18/8 stainless steel with a sweat-free finish and dishwasher-safe construction, offering a rugged yet tidy solution for hydration on trails, at the campsite, or during everyday commutes.

How does the Cup Cap attach to my Rambler Bottle?

The Cup Cap securely fastens to the threaded mouth of any Rambler Bottle model so the cup stays with the bottle in transport. Installation is simple and tools are not required; the cap threads on like a standard bottle top and locks in place for travel.
