Any tumbler that's coming along for the ride needs to be tough enough to keep up. The NASH x Yeti Tumbler is made from durable stainless steel with double-wall vacuum insulation to protect your hot or cold beverage at all costs.

While the magnet on the included MagSlider™ Lid adds an additional barrier of protection for keeping drinks contained and preventing heat or cold from escaping, please note - this magnet component is not leakproof and will not prevent spills.
