I purchased one of these expanding backpacks for a trip to Europe this summer. And immediately my wife wanted one as well. Great product!
The bag I was looking for, but didn't know where to find. Or if it even existed! Compartments are well thought out. Love the optional expansion to a much larger bag. Construction and materials are first-rate; couldn't be happier.
I love my Knack bag! Customer service is top notch.
We had a trip planned to fly to New York and purchased the medium size. Once fully expanded, I was really impressed with how well it fit under the airline seat in front of us. With the shoulder straps tucked away, it slid in and out easily, making it convenient to quickly grab our electronic devices and store them again during the flight. Great design, practical, and perfect for travel!
Purchased a bag as a gift for my adult son. It works as a "work-bag" but it can expand significantly to a weekend backpack/bag. My husband was so impressed that he has requested a backpack/bag as well. Highly recommend these products for high-use, on-the-go adults wanting one bag that will serve multiple uses.
The company executed a flawless exchange and I received the item I wanted in a timely way. Good, responsive customer service. I am very happy with the product which I believe will suit my needs for years to come.
White backpack has black panel on the back, which is absolutely not obvious from the website - one photo shows is, others show white panel. Misleading and disappointing.
Hi, Apologies for any confusion the photos online caused. The picture of the full black foam panel is the correct color as opposed to the side shot of the Oatmilk Knack Pack. Fortunately, we offer free, 30 day, no-questions asked returns. So if you find the Knack Pack is not to your liking within this time period, you are welcome to return it for full refund.
A well made bag for a long haul trip. Perfect amount of pockets both hidden and exposed. The expandable section is ample without being too big or unmanageable. Comfortable to wear or hold.
Best travel backpack system by a long shot! Extremely flexible and holds a ton of stuff!
I've been using Knack Packs for about 5 years and there is not a better product or customer service on the market.
Responsive, friendly, helpful customer service and a solid bag!
I place the order, had a few questions. I called minutes after my order and left a message. Got a call back in less than 5 minutes. I spoke with Racheal on the phone. What a superstar! She reviewed my order, sent a note to the warehouse and really helped me out. She saved the day. Have not received the item yet, but based on the customer service I'm sure the quality is just as good! Thank You Knack
This will be my second Knack bag. I love my bag! Will seriously have a hard time saying goodbye to my gray one that has been with me almost every day for 7+ years. But it is time for a new one. Also, excellent customer service when I reached in August with a question.
Great Quality, and the site is easy to navigate.
I bought a medium Series 2 and then decided on a Series 2 large. Exchange was easy and they were very responsive.
Hi, Thanks for your order. In response to your comment, Knack discount codes are only applicable for full priced items. Your purchase was for a bundle, which is already discounted. This means discount codes cannot be applied for further discounts. Please reach out to [email protected] if you have any further questions or concerns.
I was really excited to use my travel backpack for my upcoming trip to Italy. However the bag appears to be scheduled for delivery on my day of departure and I won't have a chance to use it. I had to subsequently purchase something else but Customer Service was very helpful to authorize a return / credit when I return from my trip.
As stated at checkout, order transit time is 2-6 business days. The 5 business day transit time for your order is within our estimated time period. We are sorry our Knack Pack won't arrive in time for your trip, but we wish you safe and happy travels.
