Overview

A magnetic shield across the opening snaps shut with a push and stays open while you load, which is how this YETI backpack cooler resists leaks. Closed-cell foam holds the cold, and the bundled refreezable ice block cuts down on loose ice.

Backpack straps free both hands for carrying chairs or a kid. The magnetic top opens fast without a zipper to fight. Exact size, empty weight and hold time are not listed.

Who it's for

Hikers, beachgoers and parents carrying gear will appreciate the hands-free carry. Larger groups or multi-day trips need a bigger hard cooler.

Pros and cons

Pros
  • Hands-free backpack carry
  • Magnetic leak-resistant top
  • Closed-cell foam insulation
  • Refreezable ice block included
Cons
  • Dimensions not listed
  • Hold time not stated
  • Smaller than a day-trip cooler

Performance notes

Closed-cell foam slows heat transfer through the walls, and the magnetic shield seals the top to stop leaks. Pre-chilling the cooler and using the ice block alongside ice extends cold time. Keeping it out of direct sun helps.
