The YETI TANK®is a highly portable party machine designed for advanced beverage distribution, but we wanted to make it even better. Available for both the YETI TANK 45 and YETI TANK 85, the YETI TANK Lids are made of UV-resistant, marine-grade material. You can keep your beloved party tub even colder while moving it from place to place or use the Tank as an extra seat or cutting surface.
