Our Story

Lurking in the shadows of Seattle, WA, Mt. Rainier stands at 14,411 feet and is the most glaciated mountain in the continental United States, making it one of the world’s most technically challenging climbs. In 1972, JanSport began a tradition of bringing employees, retail and industry partners, athletes and guides together for an annual climb to provide product feedback and continually push technical product advancement.

The JanSport Guide Series pack, the result of research and rigorous testing with International Mountain Guides, is designed to be the best in class mountaineering pack for guides around the world.
