Description

With the ability to switch from laptop duffel bag to everyday laptop backpack, the Convertible Duffel bag fits all your journeys. Used as an expandable duffel bag, a simple zip increases its capacity by over 67%, from 24 liters to 40 liters, so it has room for up to a week of clothes. Carried as a backpack, its padded 15.6” laptop pocket, protective fleece-lined tablet pocket, and tons of internal organization pockets make this a great everyday work bag. Constructed with lightweight, yet durable, high density nylon fabric, the Knack Convertible Duffel bag is truly a “do it all” bag for on-the-go professionals.
