The YETI Tundra® and Roadie® meet the Interagency Grizzly Bear Committee (IGBC) standards for bear-resistant containers when used with extra-long shank Master locks. Our hard coolers have been thoroughly tested in both controlled bear simulations and with wild grizzly bears. When the Yeti Bear Proof Locks are used properly, grizzlies get nothing but frustrated after coming across your cooler.
