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.

Shop Water-Resistant Backpacks FAQs

Can I use my Knack Bag in the rain?

While not waterproof, you can use your Knack in rain showers and the contents of your bag will stay dry. Knack fabrics and zippers are designed to resist water penetration while you look to get out of the rain.
What materials make Knack Bags water resistant?

Knack Bags use custom-designed exterior fabrics with water-resistant surface finishes and a PU coating on the back. This combination helps repel water, dirt, and stains.
How should I care for my Knack Bag to maintain its water resistance?

To keep your bag’s water resistance effective, clean the exterior with a damp cloth and avoid machine washing, which can strip away the protective coatings.

Will my electronics and valuables stay dry inside a Knack Bag?

Your electronics and valuables will stay dry in light rain or brief exposure to moisture. For extra peace of mind, especially in unpredictable weather, store sensitive items in internal pockets or use additional waterproof sleeves. Remember, Knack Bags are not designed for extreme conditions or full submersion, so plan accordingly if you expect to encounter any full water submersions.

Testimonials

Put this bad boy to the test three days after I got it. Rain while training and documenting Marines at Quantico, this bag took it all like a champ. Travels well too. It fit my 16 inch and 14 inch MacBooks (both with rugged cases), my boxed Magic Keyboard, my Magic Mouse, my Canon Camera, a 28mm lens with case, my flash, my Joby mini tripod, 2 sets of news crew lav mics, a rode mic, and a toiletries bag. Anddddddd it wasnt even remotely full! I only filled up the front pockets and not the clam shell portion. The water bottle pocket was nice and fit my 18 oz. Brita waterbottle.

The entire whole knack series has a huge number of uses. I am a long time traveler with years of experience. Sometimes I use one bag, sometimes a bag and 2 suitcases. If given the chance, that bag is always this one.

Whether you're going to school, a working professional, going on overnight trips, or transporting items, this bag has ways to make your life easier. It will not help you in a torrential downpour but does repel light rain.

I got this Knackpack when I started my MBA at the Wharton School. I didn't realize what a cool pack it was until I started using it. After a year of traveling across the country for work and class, it still looks brand new. It has been rained on, thrown under airline seats, and stepped on in the classroom. I literally carry it every day, but you'd never know. It holds its form well, protects all my stuff, and has the perfect amount of space to pack for a workday (when not expanded) or a three or four day weekend (when expanded). The backpack that is changing the backpack. Great job, Knackpack!

I purchased this bag in March - just as the US went into lock-down ... I don't want to brag, but we did go outside to my backyard this one time and did work on the back patio. I had to work on something else so everything was put back in the bag but left the bag on the table. It started to rain and I'm proud to say the few minutes it was outside did not damage any of the things inside the bag (no water through). Not sure if this was by design, but just feedback - it appears a small rainstorm won't affect your contents.
