We like to think of each Knack Pack we design as one of our kids. So, it’s impossible for us to choose one over the other. Go ahead and choose what works best for you (just don’t ask us to take sides).

Series 2

While it shares the same great everyday organization and travel features with its older sibling, our new Series 2 collection looks very different. From its leather-wrapped touch points to its redesigned organization compartment, this new member of the Knack family stands on its own. Compare Sizes

Series 1

The collection that launched Knack and One Bag Life. Our original expandable backpack collection was the first to offer the singular combination of professional style, around-town function and patent-pending travel capabilities. Compare Sizes

Series 1: Leather

Our best-selling Series 1 Knack Pack now comes in soft, luxurious Napa leather. Beautiful, yet surprisingly practical too. Over time, this supple, full-grain leather will develop a warm, rich patina that is unique to you and your backpack. Compare Sizes


Knack’s collection of modern backpacks redefines what a professional backpack should be. We started Knack with the premise that days are hectic enough without having to carry several bags at the same time. So, each of our lightweight, modern backpacks not only provide great everyday carry function, they also offer patent-pending travel function in the same bag. One Bag Life is finally here.
