Wallaroo Hat Company is based in Boulder, Colorado. The company has been awarded the "Best of Denver" from Westword magazine and was listed as a Top Women-Owned Business in the Daily Camera.

Wallaroo Hat Company was founded by Stephanie Carter and Lenya Shore in April 1999 after they discovered the Australian secret to sun protection with style: colorful UPF 50+ crushable fabric hats.

They began wearing them around Boulder, a city known for its outdoor lifestyle and more than 300 sunny days each year.
