YETI Tundra 350 Cooler

The Tundra 350 is a very large commercial-grade cool box for deep-sea catches, catering, larger events or serious group trips. It is much bigger than most families need for a beach day or picnic. If you want something easier to lift, store and move around, a smaller Tundra or wheeled Roadie may be the better choice.

This is YETI’s biggest hard cooler, with over 300 litres of space. It can take a very large load, including sizeable catches, food for events or a serious ice setup for extended trips. For planning purposes, it is worth measuring your storage space carefully and thinking about how you will load, lift and transport it when full.

No, not in the way a smaller cooler is. This is a two-person lift, especially once loaded with ice, food or fish. The rope handles help with carrying, while non-slip feet and tie-down slots make it practical to secure on a boat, trailer or vehicle. It is best treated as a fixed base cooler rather than a grab-and-go option.

The Tundra 350 includes one removable dry goods basket, which is useful for keeping produce, sandwiches or smaller items raised above meltwater. The main compartment is built for bulk cold storage, so the basket is a handy extra rather than a full organiser. For mixed loads, use separate containers or bags inside to keep food and catch apart.

After a trip, drain meltwater through the drain system, then clean with warm water and mild washing-up liquid. For heavier cleaning, use a suitable diluted bleach solution and a sponge or mildly abrasive cloth, then rinse and dry before storage. Do not leave fish residue, salt water or food spills sitting inside, especially if the cooler is being stored closed. See our YETI cleaning guide for more detailed care advice.
