History.
JanSport was founded in 1967 in Seattle, Washington, USA by Murray Pletz, his wife Janis "Jan" Lewis (for whom the company is named), and his father Norman Pletz. JanSport innovated with a panel-loading daypack, unlike traditional top-loading packs.
In 1975, JanSport introduced the first convertible travel pack, as well as its signature daypack. 
In 1972, the founders began inviting their friends to join their climb on Mount Rainier to what is now known as the longest consecutive group climb. To this day, Jansport still holds the record of the most consecutive annual group climbs. In 2018, was their 46th annual Jansport Mount Rainier climb consisting of a team of 16 employees, retailers, international distributors, non-profit partners and media. 
In 1986, VF purchased JanSport's then parent, Blue Bell.
JanSport's corporate headquarters is in Greenwood Village, Colorado, at VF Outdoor headquarters, where it shares offices with divisional siblings Lucy and The North Face. A distribution facility in Everett, Washington, which had opened in 1971, closed in March 2012. JanSport's collegiate apparel warehouse in Appleton, Wisconsin closed in 2017.
JanSport started by developing the external frame backpack which used a metal frame with a cloth packsack attached to it. The products made include technical day packs and internal frame backpacks. Up until the early 1990s all JanSport packs were made in the United States.
