Inspired by the oversized beer steins everyone loves, the Igloo® 1L Party Mug keeps brews (and any beverage) frosty from first pour to last sip. Its double-wall, copper-lined stainless steel body delivers long-lasting hot/cold retention, while the leakproof Flip ’n’ Sip lid opens effortlessly and locks into place. A sturdy side handle ensures easy carrying, and intuitive features - like the no-look sip indicator and built-in rubber coaster - make it ideal for use around the campsite, backyard or tailgate. With a generous 1-liter capacity and a sweatproof, easy-clean design, this reusable mug is built for serious sipping.
