What to know before buying

The listing describes the bag as waterproof in its specifications and as water-resistant in feature text. These claims are not identical, so do not assume submersion protection. Confirm the desired protection level before use in wet conditions. The displayed 24"L x 9"W x 9"H dimensions also appear unusually narrow for a 70-liter bag, so confirm the selected listing's size details if fit matters.

Customer feedback highlights capacity for extended trips, perceived build quality, water resistance, useful pockets and the convertible strap setup. Customers also describe using it for flights and weekend trips, including airport walking. These reports align with the listed 70-liter capacity and backpack-conversion design, but the contradictory waterproof and water-resistant wording means customer impressions do not establish a specific level of water protection.

Frequently asked questions

Can the Thule Chasm be carried as a backpack?

The listing says it converts from a duffel to a backpack using removable straps that tuck away when not in use.

How much can it hold?

The listed capacity is 70 liters. The listing also gives dimensions of 24"L x 9"W x 9"H, which appear inconsistent with that capacity, so confirm the size details if they are important.

Is this bag fully waterproof?

The specification field says “Waterproof,” but feature descriptions call the materials weather-resistant or water-resistant. Treat the protection level as unconfirmed and do not assume it is suitable for immersion.

What organization features are listed?

The bag has internal mesh pockets and an exterior stash pocket, alongside a wide-mouth opening for access to the main packing area.
