Big for outdoor adventures, camping in the backcountry or filling up at brewpubs.

Featuring the ENGINE710 logo on the front and the Earthwell logo on the back, the 945ml Insulated Kewler™ flask with Bottle Opener cap keeps water iced up to 72 hours and hot drinks hot up to 20 hours. This vacuum insulated travel flask can also be used as a growler to keep beer cold up to 32 hours.

Topped with Earthwell’s patented and insulated Bottle Opener Cap, it opens beer bottles on the fly thanks to an integrated church key. It’s also easy to transport thanks to a bottle leash with room for a two-finger carry.
