Clunky zippers that snag, with teeth that catch, have troubled wearers since the earliest iterations were invented in the 19th century. TRU Zip is toothless, waterproof, dustproof, snag-resistant, and submersible, using both mechanical and vacuum forces to create a virtually impenetrable seal. 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
