Highly recommend, awesome bag!

Few weeks in and loving it. Perfect spread of features, pockets etc. Haven't fully tried expandable section yet, but looks good for 3-4 days of travel.

Knack team - couple ideas:
- the large bag that the backpack comes in - why not put drawstrings in it, so you can use it as a backpack (for hiking, beach etc., where you wouldn't take the Knack)
- why bug so soon after getting the bag, vs giving some time to use and get a real feel for it? Could even ask what/when/where my next cool trip is, during the order/checkout process. Peeps could share and you could ask them after that, giving you real life scenarios of how/where your gear is used.

Perfect size!

I purchased the Medium Expandable specifically to carry my laptop on a recent trip. It fit perfectly. Although I didn't use the expandable feature, I was able to fit quite a bit of things.
This is a very sturdy bag and is comfortable to carry.

Really happy with this bag

Really happy with this bag. I purchased it hoping it would truly serve as both my daily commuter and a travel bag. It absolutely does. I use it everyday and have already taken it on 3 different trips. While I do wish the internal pockets/organization had a few more options or details, the overall usability and quality of the bag are outstanding. This will be my go-to bag for a long time.

The Best Travel Backpack ever!

I got this from my company and didn’t really look at it until months later. They normally send us backpacks and figured it was just an average, same as the others. Oh boy, I was wrong!

The Knack is so AMAZING! I travel quite a bit for work and hand down, this is the best pack that I’ve owned. There are just the right amount of compartments to keep me organized. I love that there is a luggage section for those quick trips. I like the option of having straps and more importantly, being able to put them away. The expand feature is a fantastic option and the Knack isn’t at all bulky. It’s durable, looks great and keeps me well organized.

For me, I don’t think that I’ll ever own a different backpack other than a Knack!

Thanks Knack- for a engineering an the Best travel backpack!

Did SO much research and this is the best backpack I've ever had

I spent forever searching for the perfect backpack and even bought and tried several before finding Knack. Honestly this bag is perfect and I couldn't be more happy!! 10/10 recommend.

This is a great travel bag. I go back and forth between 2 homes every 2 weeks and this is perfect. I always have my 2 dogs with me so having hands free is necessary. I can pack a weekend's worth of clothes plus my essentials (laptop, phone, sunglasses, tickets etc.). The only thing I wish it had was a bigger pocket for a water bottle (it fits a 500ml bottle), but I haven't really found another bag that does either so I think it's pretty standard. Otherwise the bag is perfect. Great quality, nice looking and keeps me organized.

Great bag

First trip, this bag was great. Plenty of storage pockets. This is a great 1 to 2 day carry on bag. Love the expandable option.
