Stainless steel tumblers usually leave a tangy taste in your mouth, but the Yeti Rambler Tumblers steer clear of such stainless steel stereotypes. The drink tumblers are "over-engineered" and boast BPA-free kitchen-grade 18/8 stainless steel and double-wall vacuum insulation. Have you ever heard of such an elaborate drink container?
The best part of the tumblers is that they keep your drinks "as cold as science allows;" they keep ice 2x longer than plastic tumblers and are designed for maximum ice retention. You won't ever have to worry about a warm beer this summer and can sip at your preferred pace. Amazingly, the same concept goes for hot beverages too; the tumblers have no problem maintaining piping hot drinks.
