[citation needed] In 1998 Ian Ivarson conceived and designed an internal shelf system for backpacks with an aim to create better organization and weight distribution ergonomics.
At the time, Ivarson was a high school student at Marin Catholic in Kentfield, California.
Early prototypes were developed with a sewer in Berkeley, California, and eventually progressed to direct relationships with unionized factories in Asia.
Following graduation from the University of Denver, Ivarson launched IVAR in July 2006 with one single daypack model from an office and warehouse on Bank Street in San Anselmo, California.
Today, the brand is sold primarily online and in an array of brick-and-mortar retailers in the sporting goods, outdoor, luggage, and bookstore categories.
