Bobber Bottle

A stainless steel bottle for everyday hydration — water stays cold up to 20 hours and coffee hot up to 10 (770ml). Double-wall vacuum-sealed, sweat-free, and tastes of nothing but your drink.

Most everyday bottles condensate against your bag, taste of metal, or lose their cool by midday. The bobber Bottle is double-wall vacuum-sealed 18/8 steel — the outside stays dry, and the inside tastes of nothing because nothing plastic touches your drink.
