Why Get a Front-Loading Backpack?

Frequent travelers know the convenience of a front-loading backpack. It’s common with top-loading backpacks to have to dig to the bottom of your bag for a lost item, which messes up your entire organization. On the other hand, front-loading travel backpacks unzip like a suitcase so you can access everything at once. Although it’s hidden in the back, Knack’s expandable suitcase compartment has the same benefit. Plus, our carry-on backpack sizing saves you time and money at the airport. Make your trip easier by shopping Knack today.

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.

Front-Loading Backpacks FAQs

What does “front-loading” mean, and how is it different from regular backpacks?

A front-loading backpack unzips like a suitcase — the main compartment opens fully, letting you see and access everything without digging to the bottom. Knack’s version hides the suitcase-style zipper in the back, combining the convenience of full access with sleek design. This makes packing, unpacking, and staying organized much easier for travel, business, and everyday use.
How much can these backpacks expand, and how many outfits or items can I fit?

Honestly, this depends on the size of the bag. Our front-loading backpacks feature a patented expandable suitcase compartment that gives you up to ~50% more carrying capacity when you need it. Depending on style and how you pack, you can fit roughly 3-4 changes of clothes plus laptop and accessories, making them great for short trips or carry-on travel.
Will this backpack fit my laptop? What laptop sizes are supported?

Yes — each model lists which laptop sizes it supports. Please visit the specific backpack you're interested in to know exactly what laptop size each bag supports.
Are these bags okay as a carry-on or for air travel?

Absolutely. Because of the front-loading design + expandable compartment, these backpacks are made to maximize space while staying within most carry-on size limits. The ability to expand when needed helps avoid overpacking and fees. Plus, with features like a hidden trolley sleeve, it's easy to slip over luggage handles and move through airports more smoothly.

I’ve used my Knack backpack for the last 4 years traveling around the world and back home, and it’s still going strong. My Series 1 Backpack is sturdy and reliable, and their customer service was great when I needed replacement tabs. Really appreciate a company that stands behind its products. Would highly recommend it for daily and extended travel.

As a flight attendant I am aleays looking for sustainable and practical packing solutions. This bag is exceptionally practical and convenient. Initially, I had concerns about its size, but it has proven to be ideal. It comfortably fits on top of my carry-on and is secured to the handle using the convenient slit on the back of the bag, ensuring that all my documents and devices remain within easy reach. I highly recommend this bag
