Great overall bag with lot's of… Great overall bag with lot's of capacity when expanded but also a slim profile when zipped up. Very comfortable and clearly high quality design and manufacturing. Happy overall. Two things I would put on my "wish list" 1) an easy access external pocket. 2) a better mesh pocket system for cables. Right now you just have to drop the larger cables i.e. Mac power cords into the based of the front pocket and dig it out along with the rest of the cables when you need them.

Stop blasting me with repeated emails… Stop blasting me with repeated emails asking for reviews. The product won’t be delivered until Dec. And I certainly don’t want to be prompted again. If you’re genuinely honest about wanting reviews, you need to read, post, and heed this feedback. Knock it off. Your review fetish is irritating noise for your customers.

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!

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.
