Very easy to navigate the website Very easy to navigate the website. Pictures and dimensions helped make the perfect purchase. Waiting for our knack backpack to arrive!

Exceeds Expectations Great product! I was a little hesitant to spend the money on the V2 Large Pack, but I'm so glad I did. It works great as a personal item for my business air traveling, along with the pack accessories I purchased. Between this product and my carry-on, I can pack everything I need for an extended trip.

Fast shipping and excellent product! Fast shipping and excellent product! The small expandable pack is perfect. Wise design and well made. As a 70+ woman traveler, I pack light to go to Europe often with only carry on luggage. This pack is the best.

Fantastic Product and The process was smooth and informative. The KNACK website provides various product info and allows easy comparison of their bags to determine what product will meet ones needs. The picture of the product on a persons back was extremely helpful since there were models of different heights. The bag itself is fantastic! It is sturdy, sleek and offers plenty of room. Once the extra storage section is opened, there is so much that can be put into the bag. I was able to pack 4 days of shirts, undergarments and socks into 1 small and 1 medium KNACK packing cube, which fit perfectly in the KNACK expandable section

I cannot actually vouch for the product… I cannot actually vouch for the product I purchased, since I haven’t received it yet, but I can vouch for the customer service. Top notch. I made a mistake with the shipping address and immediately noticed after placing my order. I reached out to customer service and I was able to get my address updated, and that made me very happy.
