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.

Carry-on Backpacks FAQs

Can a 45L backpack be a carry-on?

Most U.S. airlines use a bag’s dimensions in inches to determine its carry-on eligibility. Rather than the bag’s total volume, try measuring its height, width and depth when full. The most common maximum carry-on size in the U.S. is 22" x 14" x 9". It’s always good to double check your airlines carry-on specs.
Do expanded Knack Packs fit under airplane seats?

Expanded Small and Medium Knack Packs fit underneath most U.S. seats, while expanded Large Knack Packs fit in overhead bins. International flights tend to have smaller carry-on baggage sizes, so double check with your airline.

Are all Knack Packs carry-on friendly?

Knack Packs are designed to meet U.S. airline carry-on requirements. However, it’s good to check your specific airline’s carry-on requirements, especially for international travel.

Do Knack Packs make good carry-ons?

Knack Packs are designed to be convenient carry-on backpacks. Carry-on friendly dimensions, integrated trolley sleeve, tuckaway shoulder straps, side handles and easy-access pockets make them the most ideal bags for air travel.

Testimonials

I have the Series 2 in grey, and I'm in the middle of my third, 1- to 2-night trip with it as the sole bag. I love the clean, contemporary design and material quality; plenty of well-organized room for everything I need –– including two laptops (one 15", one 13") in the sleeve. Even when travelling with a suitcase, this bag is and will be my carry-on / underseat bag of choice.

From working as a traveling MA, to taking weekend trips across the country, to traveling overseas, to now medical school, this backpack has consistently been amazing. I have so many positive things to say, but to just pick a few, the expandable compartment is so useful when I need it and so easy to forget when I don't, the exterior and interior have held up far better than any backpack I've ever owned, and the layout of all the pockets is so well designed...

I love this bag. The organizational capabilities of this bag are phenomenal, it has high quality materials, it fits under the plane seat even when completely filled, and has more space than I could have ever thought it would. I started to buy the large, but I'm happy I bought the medium because it was perfect for my trip.

I was looking for a travel backpack that could be well organized and not embarrassing to use for work when I reached my destination. For years I have been traveling with an additional nicer-looking tote to use while at meetings, but this takes up space in my luggage and I wanted to consolidate these functions. This backpack does the trick! Very well organized, light, and not ugly/utilitarian looking while at meetings.
