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

I am an admitted bag junkie. I have spent years - decades, really - bouncing from bag to bag looking for that elusive combination of form and function, style and utility, built for an urban commuter and traveler that (a) like to carry a lot of stuff, (b) wants that stuff really well organized, and (c) likes looking good while doing it. I hemmed and hawed on this bag, ordered it twice and canceled, and then took the plunge when the new line of colors was introduced. Nothing against grey and black, but I'm a guy that likes a bit more flair. The Knack Medium Series 2 Expandable Pack has exceeded every expectation and checked off boxes I didn't know I needed or wanted.

My Knack bag is perfect!! A space for everything and the zippers are strong and quality! (quality zippers are so important when you stuff your bag!). I've gotten many compliments on this color too!

Nancy M.

This is the first backpack I've bought in a couple of decades, as I grew more comfortable with the messenger-style bag, but it's lived up to all the promises made in flexibility, organization, and comfort, and as a bonus, my back isn't killing me after carrying it for a couple of hours. Look forward to a long future with Knack.
