Knack bags have a knack for great products I have been travelling my medium expandable backpack which combined with 3 medium compression cubes makes packing a breeze. Totally recommend it as part of your travelling kit.

The Best work backpack! ordering is simple, delivery is exactly as they say. This is the best work backpack I've had. I love how it's also like a GO BAG, as I have an extra set up clothes in the hidden middle compartment just in case I don't get home or I spill something on my clothes while I'm working. Built well, amazing customer service when needed.

I reached out to customer service… I reached out to customer service inquiring which bag would be good for me, and they provided me with two options, and were very honest of the capabilities. I ended up buying the bag and I’m super excited.

My order was fulfilled quickly and… My order was fulfilled quickly and received a few days after placing the order. The backpack (Series 2, small) is exactly what I needed, a companion to a regular size carry-on. This is quality backpack and I am very pleased with it and with the service.

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.
