The 40L Thule Chasm is a rough-and-ready duffel bag that can be thrown into your trunk or roof box, perfect for short trips or multi-day adventures. The 2-in-1 design easily converts from a duffel to a backpack, and the backpack straps tuck away when not in use. Staying organized has never been easier thanks to the internal mesh pockets, an external carrying case that doubles as an accessory pouch, and external compression straps. Built for durability, the Chasm is made using 100% recycled, weather-resistant tarpaulin fabric, and has a padded bottom to protect your belongings.
