YETI Rambler® 20 oz (591 ml) Stackable Cup with MagSlider™ Lid - Seafoam

The YETI Rambler® 20 oz (591 ml) Stackable Cup with MagSlider™ Lid is a true daily driver, built to handle everything from early-morning coffees to evening beers around the fire. Designed to be cup holder compatible and easy to live with, it’s the sort of cup you’ll reach for without thinking, at home, on the road, or outdoors.

Crafted from 18/8 kitchen-grade stainless steel, this cup is puncture and rust resistant and tough enough to handle serious use. Its double-wall vacuum insulation keeps hot drinks hot and cold drinks cold right through to the last sip, making it equally suited to steaming brews or ice-cold lagers.

The included MagSlider™ Lid adds splash resistance for drinking on the move, while still being easy to open and clean. It’s worth noting that the magnetic slider is not leakproof and won’t fully prevent spills, making this cup ideal for hands-on use rather than being thrown into a bag.

Designed with space-saving stackability, the Rambler® 20 oz Stackable Cup packs efficiently whether you bring two or ten. It’s also dishwasher safe for hassle-free cleaning and BPA free, backed by a 5-year warranty for long-term peace of mind. Empty weight is approximately 0.3 kg, with dimensions of 8.9 cm wide by 16.5 cm high, robust, practical, and built for everyday adventure.
