Field Tests

The IGBC has become the Gold-Standard in Bear-Proof Testing. National Parks and Forests across the nation look to the IGBC for their stamp of approval on bear resistant products. 

While walking through their facility you will find yourself in the "graveyard" which is littered with prototypes ranging from personal food storage, coolers as well as trash cans and dumpsters that didn't make the cut. 

Ursack products are put through the most rigorous live bear testing in the world. Tucked up under Montana's chin just outside Yellowstone National Park, there is a facility called the Interagency Grizzly Bear Committee (IGBC), where injured and trouble bears are rescued from euthanization, rehabilitated, and live out the rest of their lives.

You will find our IGBC approval number and their stamp on all of our bear resistant bags. For soft sided containers such as ours, any hole that exceeds 1/4 inch is considered a failure, and that product has to go back for redesign before testing again.
We understand that bears are extremely smart, also that time and determination can sometimes mean that products will fail in the field, but we stand behind our products with our Limited Lifetime Warranty, and will replace any Ursack bag that doesn't meet that 1/4 inch standard in the wild.
