help Thule Chasm 40L FAQ

Is the Thule Chasm 40L waterproof or water-resistant?

The Chasm 40L features a TPU-coated 900D polyester fabric that provides water-resistant protection against rain and splashes. It is not fully waterproof, so submersion should be avoided. For extreme wet conditions, additional waterproof dry bags inside are recommended.

Can this bag be used as a carry-on for most airlines?

At approximately 22 x 14 x 11 inches, the Thule Chasm 40L fits within most domestic airline carry-on limits. However, airline dimensions vary, and the unstructured shape may differ from strict size-checkers. Always verify with your specific carrier before flying.

How comfortable are the backpack straps for carrying heavy loads?

The backpack straps are functional for short distances but lack substantial padding. They work well for 10-20 minute carries from vehicle to campsite. For extended hiking with heavy loads, a dedicated hiking backpack with hip belt support would be more comfortable.

What is the difference between Thule Chasm and Thule Landmark duffel bags?

The Chasm prioritizes rugged simplicity with its wide-mouth opening and minimal organization, while the Landmark includes a Separato divider system and additional external pockets. The Chasm is slightly lighter, and the Landmark offers more specialized storage options for organized travelers.
