Save some space by transforming your Rambler Bottles with our heat-locking, two-in-one companion — the Cup Cap. Not only is it compatible with every Rambler Bottle, but it also offers twice the functionality. As an insulated cap, it helps keep your coffee, tea, or even whiskey at the perfect temperature. And when you twist it off, you’ve got a double-wall vacuum insulated cup.
18/8 Stainless Steel
Puncture- and rust-resistant from top to bottom thanks to its kitchen-grade stainless steel construction.
No Sweat Design
Keeps your hands dry and unaffected, no matter how hot or cold the beverage inside the bottle (or cup).
Because no one needs more work to do.
Every angle is the right angle
Over an inch of lid insulation keeps temperature retention on lock.
Carry it with confidence.
