Overview
The Yeti Rambler 36 oz bottle pairs vacuum-insulated stainless steel with a leakproof Chug Cap that opens on a half twist of the TripleHaul handle. It suits anyone who wants a single rugged bottle for a full day away from a tap, without fussing over a straw or flip lid.
Yeti built its reputation on cooler-grade insulation, and the Rambler carries that into a bottle sized for a full day away from a tap. The Chug Cap swaps a sip spout for a wider opening that empties in a couple of gulps and is easier to fill with ice than a narrow straw lid. At 36 oz it sits between a gym bottle and a jug, a size meant for refilling once rather than constantly topping off.
- Vacuum-insulated stainless steel construction
- Leakproof Chug Cap with quarter-twist opening
- 36 oz capacity
- TripleHaul carry handle built into the cap
Who it's for
This suits someone who wants a single durable bottle for a car cup holder, gym bag, or job site and does not want to fuss with a straw or flip spout. It is not aimed at anyone who wants ounce markings, a straw option, or the lightest bottle on the shelf.
Strengths and trade-offs
Drawn from this product's published specifications.
- Wide Chug Cap opens with a half twist
- Stainless steel build resists dents and drops
- 36 oz size covers a full day without refilling twice
- TripleHaul handle doubles as a carry point
- No straw or sport-cap option listed
- No volume markings mentioned on the body
- Steel construction adds weight versus plastic bottles
Performance notes
The vacuum-sealed double wall of stainless steel keeps contents insulated without condensation forming on the outside, the same principle behind Yeti's coolers. The Chug Cap releases with a quarter to half turn, then lifts off to expose a mouth wide enough for ice cubes or a fast pour, unlike a narrow sport-cap spout. The TripleHaul handle attaches to the cap so the bottle can be carried by hand or clipped to a bag.

Questions about the Yeti thermoses
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Is the Yeti Rambler 36 oz leakproof when the cap is on?
Yes, the Chug Cap is designed to seal without dripping once twisted fully closed, though it should still be carried upright like most twist-cap bottles.
Does the Yeti Rambler 36 oz keep drinks cold and hot?
It uses vacuum insulation between two layers of stainless steel, the same approach Yeti uses in its coolers, which keeps cold drinks cold and hot drinks hot without the outside sweating.
How do you open the Chug Cap on this Yeti bottle?
A half twist of the TripleHaul handle releases the cap, exposing a wide mouth for fast drinking or adding ice.
