About Us


Originated in 2015

Ullr Coolers was born of a love for hiking and camping along the beautiful trails of the North Shore of Lake Superior. Year after year, the same crucial question would come up: how can we keep our beers cold when heading off the grid? Carrying a traditional hard-sided cooler was out of the question, so we began designing and testing materials for a functional soft-sided product to meet our needs. 

We had an excellent time testing prototypes on trail hikes throughout Minnesota, and in 2015, we released the first Ullr Cooler: an attachable backpack cooler designed to pack in/pack out 12 twelve-ounce cans and keep them cold along the way. Soon after, the product offering expanded to include bags for growlers, and Ullr began working with regional breweries to make branded growler bags. 

Word spread, and the products caught on! Folks loved that our products kept their beverages cold and were handmade in Minnesota using the highest-quality materials. Ullr’s were just plain cooler, and new products followed like our insulated can sleeve wallets, bomber bags, and farm box coolers. With success comes other challenges, and our garage shop was no longer sufficient to meet the growing demand. Thus, in 2017, Ullr Coolers, Inc. was created with headquarters and manufacturing in Castle Danger, Minnesota.

2021 offers an exciting, new adventure for the Ullr Cooler brand

In 2021 we became a part of Superior TECH manufacturing and a sister brand to Frost River located in the Lincoln Park Craft District of Duluth, giving us access to a much larger manufacturing facility and a seasoned team of talented sewing craftspeople. Frost River is a leader in pack and bag design, and we are excited to introduce that DNA into future Ullr products.
