About Us

Our mission is to help you have warm feet!

Forty Below Ltd was founded in the 1970’s, first Incorporated in 1980,  based on the serious need to have effective foot protection in extreme cold environments.  The company founder, Bill Lokey of Tacoma, WA, built his first insulated boot covers, called “Overboots” in the late 1970’s.  After his experience of several years in Antarctica and numerous expeditions around the world, he developed the original Forty Below® Mt. Everest™ model overboot, which became known and trusted in the worldwide mountaineering community.

Today, with over 40 years of experience, the Forty Below® line of products continue to be trusted and used on the most challenging of cold weather trips and expeditions around the world.  Our goal is to provide functional insulating products for extreme environments for a wide range of users, from mountain climbers to all types of snow/ cold weather/ winter enthusiasts, both in recreation and industry.

We also make Forty Below® Brand insulated covers for bottles, specialized clothing, and a line of Forty Below® insulated covers for brewing products, as we are also active home brewers since the 1980’s.  All of our products are carefully designed, and proudly hand crafted in the U.S.A, Canada, and other very special places of this incredible world.

We take pride in helping you achieve your goals, and look forward to helping you match up our products with your activities!  You can call, write, or email us for information.
