YETI Tundra 45 Cooler - 26-Can Capacity Rugged Ice Retention

In this review of the YETI Tundra 45 Cooler we look at who will benefit most and why its standout quality is long-lasting ice retention in a virtually indestructible package. Built with up to 3 in of PermaFrost Insulation and an extra thick FatWall design, the Tundra 45 is aimed at campers, anglers, and weekend adventurers who need a portable chest that keeps contents cold for days and resists rough handling. The bottom line: if you want a heavy-duty cooler that holds roughly 26 cans with a 2:1 ice-to-contents ratio, this model delivers reliable cold storage and peace of mind.

Key Features

• Capacity: Holds up to 26 cans with a recommended 2:1 ice-to-contents ratio, making it a solid choice for small group outings.
• Insulation: Up to 3 in of PermaFrost Insulation and FatWall construction provide extended ice retention so food and drinks stay cold longer.
• Durability: Rotomolded construction makes the cooler essentially armored and capable of standing up to rough transport and outdoor use.
• Security: T-Rex Lid Latches use heavy-duty rubber and patented keeper technology to prevent busted latches and keep the lid sealed.
• Bear-Resistant: Extra thick walls and a sturdy lid design are certified bear-resistant for safer use in wildlife country.
• Included accessory: Ships with one dry goods basket for organization inside the cooler.

Who It's For

The Tundra 45 is best for outdoorspeople who prioritize toughness and sustained cooling over minimal weight; anglers, car-campers, tailgaters, and backcountry cooks who need reliable ice retention will appreciate its construction and sealing system. Its roughly 25 1/2 in by 16 in footprint fits well in truck beds and larger vehicle trunks while still being manageable for two people.

Those who should look elsewhere include hikers or ultralight backpackers who need minimal carry weight, since the empty weight is about 23 lbs. Buyers on a strict budget may also consider less expensive soft-sided alternatives that sacrifice some insulation and durability.
