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.

Testimonials

The bag I’ve been searching for. For years, I’ve been looking for the perfect bag to carry with me to work, hold my gym clothes, and also work as a weekender. This bag has all of that and more.

C.J. | Series 1 Medium Expandable Knack Bag

Better than Expected! This bag is amazing! I am a pedestrian commuter in Boston and was so tired of lugging work backpack and gym bag a mile each way every day. The Large Knack bag solves it all.

Julie E. | Series 1 Large Expandable Knack Bag

Great City Bag (Gym and Office Use). I was looking for something very specific. I go to the gym in the morning before heading off to an office job, where I have to wear a suit. So I needed a bag that could hold a suit in the morning, but not look too clunky when I go to the office. The Knack Bag is perfect.
