Flat-open Clamshell and Compression Design Make This Bag a Hit This bag is very well made with smart design and high quality hardware. I bought it for the clamshell flat opening but LOVE the compression system, which with a light load can still be compressed even if the main section has some content. A surprise that the bag comes with a waterproof cover, which has been the game changer during weekend scooter escapes on Bali during monsoon season. This is a great bag and I expect it to last a lifetime. I bought the medium with three small compression packs and it keeps me very organized.

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!

Great bag Great bag. Well made. Comfortable on the back. Organization light weight. Fits computer and all I need for a weekend away. Great color. Good value.

Customer Service Amazing and Love My Bag Customer Service was amazing! Rachel's response time and resolutions were top notch. The expandability aspect of the backpack has helped during the West Maui fires as I walked between my home and work. There are a few personal, minor design preferences that I wish could be improved on, and will go over them in a YouTube review once things settle down here. I do love my bag and am cherishing it as it was a birthday present from my family.

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.
