The brand grew out of a trip to Bali, where the founders were taken with locally made rattan goods that shaped their earliest designs — handcrafted bags produced in a San Francisco garage on roughly $20,000 of personal funds. In the mid-1990s it shifted to woven nylon and crochet construction under the name The Sak, with crochet becoming its defining signature, and expanded through Macy's, Nordstrom and Dillard's into a multimillion-dollar business; its '120 Hobo' became a brand staple.
The Sak Brand Group became a certified B Corporation in 2022, scoring 103.1 on the B Impact Assessment. Its 30th-anniversary collection in 2019, based on the '120 Hobo', directed proceeds to a fund supporting healthcare and education for female artisans in Bali.
