While working together at contemporary brand Hayden-Hartnett, Mimi Eayrs and Joanne Lee concocted a plan to launch a line of bags. Eayrs, who freelanced in the production department, was also an event planner so she was always on the go between jobs. (Lee was a designer at Hartnett and, before that, a private label accessories designer for Banana Republic.) As a mobile office is more and more of a necessity for so many these days, the two felt they had the groundwork to start a collection, so they quit their gigs at Hartnett and in September designed their first piece: a backpack based on the idea of European children’s school bags. Their line, named Eayrslee, is expanding for fall to include a simple tote, a medium-size duffel and a flat wallet pouch. All the classic pieces are multifunctional, with convertible straps that take them from cross-bodies to a backpack, or fanny pack for the wallet. Wholesale prices range from $55 for a card holder to $305 for the backpack; materials include glossed leather and waxed canvas, as well as versions in shearling.
