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.
