Clunky zippers that snag, with teeth that catch, have troubled wearers since the earliest iterations were invented in the 19th century.

Available in three sizes and fit for use in scenarios ranging from water sports to protecting medical equipment, it’s already being used by a number of outdoor product-makers. —Suyin Haynes
