The Polar Blast is an innovative smoking device that features a dual-wall vacuum-insulated stainless-steel tumbler and specially designed lid to create a one-of-a-kind ice bong. Since its launch in 2018, the Polar Blast has exceeded 100,000 units in sales. And that’s likely to climb higher with the release of the Incognito, an all-in-one version that includes a compartmentalized lid for storing all the parts and even a lighter. There’s also a built-in grinder and stash container that screws onto the bottom of the tumbler.
