Once you start keeping your liquids in vacuum-insulated stainless steel, every other drinking vessel seems like a relic of the past.

Today on Amazon, Alpha Armur vacuum insulated tumblers are on sale in the Gold Box. The best deal of the bunch is a 36 ounce bottle with a wide mouth screw top for $20. When sealed, it’ll keep ice frozen for about a day, and the big handle makes it easy to carry or attach to a bag.

Smaller 20 and 30 ounce tumblers with regular drinking lids are on sale as well. We often see similar products from other brands for a few bucks cheaper (especially in the case of the larger one), but these are still a lot less expensive than YETIs.
