YETI Tundra 45 Cooler - Durable Ice Retention for Multi-Day Trips

Our review of the YETI Tundra 45 Cooler finds it ideal for campers, tailgaters and anglers who need a nearly indestructible cooler that actually keeps ice for days. The single biggest reason to buy is its combination of thick PermaFrost Insulation and a FatWall design, which together deliver outstanding ice retention so food and drinks stay cold on extended trips. The Tundra 45 balances capacity and portability with a rugged build that will survive heavy use without fuss.

Key Features

• Capacity: Holds up to 26 cans with a recommended 2:1 ice-to-contents ratio, making it useful for weekend outings or small group trips.
• Ice retention: Up to 3 in of PermaFrost Insulation helps keep ice longer so perishables remain cold across multi-day excursions.
• Durable construction: Rotomolded construction and an extra thick FatWall design create a virtually indestructible shell that stands up to rough handling.
• Bear-resistant: The FatWall build is certified bear-resistant, adding a layer of safety for backcountry and campsite storage.
• Secure lid: T-Rex Lid Latches use heavy-duty rubber and patented keeper technology to prevent broken latches and keep the seal tight.
• Dry goods basket: Ships with one dry goods basket, so items that must stay dry have a dedicated place inside the cooler.

Who It's For

The Tundra 45 suits weekend campers, fishermen and outdoor hosts who need reliable, long-lasting cooling and value rugged, rotomolded construction. Its capacity is a good fit for small groups or families who plan multi-day trips and want to minimize melting ice.

Those who want a lighter backpack-style cooler or need a much larger capacity for big gatherings should look elsewhere; the Tundra 45 is sturdy and heavy, and its 23 lb empty weight reflects that tradeoff between durability and portability.
