Just like the original, but with a sleeker design and an updated gasket. The 355 ml / 12 oz size is perfect for sparkling water, soft drinks, and good old-fashioned beer, all kept straight-from-the-cooler cold while kicking back on the boat, at camp, or wherever good times are going down. Features 18/8 kitchen-grade stainless steel, so they're puncture- and rust-resistant. Double walled vacuum construction keeps cold drinks cold and hot drinks hot until the last sip. Dishwasher safe Twist-off gasket keeps your bottle or can securely in place.
