Series 2: Medium Expandable Knack Pack®

Is There Any Backpack Better Than This?

I had been using Series 1 for a long time, and I was 100% satisfied with its convenience and functionality. This time, I decided to purchase Series 2, and it has fully met my expectations. It is incredibly lightweight and comes with many practical pockets, making it even more convenient to use. Once again, I feel like I cannot go back to using any other backpack. My colleagues at work often tell me how stylish it looks, which makes me feel even better about using it. One more thing I’d love to add: I was really impressed by the customer service, especially Rachel’s support. You can truly feel how much the company cares about its customers. Her responses were quick, and everything—from communication to delivery—was smooth and reassuring. I was genuinely touched by her kindness and professionalism. Thank you so much.

Very happy with the bag

I have tried a few different bags and really happy with this one. Good size for every day use and travel. Very happy would recommend

Perfect Travel Pack

Love LOVE the Series 2 Medium Pack. It offers the perfect amount of storage and organization without being bulky. The expandable section is ideal for a short trip or giving you extra flexibility on a longer trip when paired with a carryon. It’s also suited for both business and casual travel. The size is just right for petite women - it’s comfortable and not too long. While I think the bag is wonderful, I was more impressed with the customer service, who went out of their way to communicate on the shipping of my order during an east coast winter storm. With a variety of travel bags out there, I am thrilled with my purchase and would highly recommend Knack to other frequent travelers.
