SPECIAL MENTION: Four years ago, Swiss bag brand QWSTION began experimenting with banana fibers from the Abacá plant. The result of that research is a line of bags made out of Bananatex, the world’s first durable, waterproof and biodegradable fabric made entirely from banana plants. Qwstion currently offers three Banatex styles, the Hip Pouch ($80), Zip Pack ($310) and Roll Pack ($340). —Megan McCluskey
