Know before you buy
Yes, it is designed to convert from a traditional duffel to a backpack. It features removable backpack straps and padded grab handles, allowing you to switch carry styles depending on your needs.
With dimensions of 20"w x 10.25"h x 12"d and a 40L capacity, it generally fits within standard carry-on size requirements for most airlines. However, we recommend checking your specific airline's carry-on policy before flying.
The interior is lined with a water-resistant material, and the exterior is treated with a PFC-free DWR finish. While it provides excellent protection against light rain and splashes, it is not fully waterproof and should not be submerged.

The bag is built from a combination of 200D, 400D, and 1680D recycled nylon, making it both lightweight and durable. It is constructed in a Fair Trade Certified factory, ensuring ethical manufacturing standards.
