Water-Resistant Backpack Features

  • Keep Dry

    Custom-developed, water-resistant fabric with PU coating makes water bead off. Reverse-coil YKK zippers prevent water from seeping through and soaking the important things in your bag.

    Separate, patented, expandable suitcase compartment makes packing for travel easy by giving you 50% more carrying capacity. Depending on style, hold up to 4 changes of clothes with an easy-access suitcase lid.

  • Stay Organized

    Keep all your gear secure and easy to find with next-level organization, including a fleece-lined tablet pocket, mesh accessory pockets and a hidden side-zip water bottle pocket.

About Knack

Knack sprang from the simple observation that too many people were carrying too many bags at the same time. This aha moment spurred our passion to live a One Bag Life. So we pulled together a dedicated group of frequent travelers and bag enthusiasts––from Tumi, Coach, North Face, Samsonite, and eBags––to create the one bag that’s clever enough to replace two.
