Yeti Tundra 35l cooler

The Yeti Tundra 35l is an icebox with just the right size for solo trips or feeding a small group of adventurers. It boasts up to 7.6 cm of PermaFrost insulation and a roto-moulded construction for exceptional performance adventures. It also fits perfectly into a life jacket, making it the perfect portable cooler to float down the river. To optimize the duration of temperatures, it is advisable to use YETI ice packs in combination with regular ice that can be purchased at the supermarket. The ratio should be at least 1/3 of the cooler’s capacity filled with ice; to avoid temperature fluctuations when opening and closing the cooler, it is recommended to use a towel to fill any empty space (if it is not completely full). Based on personal experience, if these guidelines are followed, the minimum duration is 3 days.
