TOP OFF YOUR YETI TANK® ICE BUCKET WITH OUR UV-RESISTANT LID. The YETI TANK® Bucket 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 create an extra seat or cutting surface.
