Duffel bag Thule Chasm TDSD302 40 L — Polyester, Grey, 580×335×280 mm

The Thule Chasm is a rugged 40 L duffel bag designed for travel and outdoor use. Constructed from durable polyester and weather-resistant tarpaulin fabric, it offers a large, wide-mouth opening for easy packing and internal mesh pockets for organizing small items. The bag converts into a backpack with tuck-away straps, includes external compression straps to keep contents secure, and features oversized grab handles and a padded bottom for protection when lifting or setting down.

Advantages

The Thule Chasm combines recycled materials throughout its exterior and interior fabrics with a robust, weather-resistant construction. Its 2-in-1 design provides flexibility between duffel and backpack carry modes, while internal and external pockets with compression straps help keep gear organized and in place. A carry case is included that doubles as an internal accessory pouch.

Suitable for

• Short trips and weekend travel
• Multi-day outdoor adventures
• Transporting gear in a car trunk or rooftop box
• Commuting when you need extra capacity and weather protection

When it may not be suitable

The Thule Chasm is not intended as a technical mountaineering pack and lacks the rigid frame and specialized support of larger hiking backpacks. For extended backpacking trips with heavy loads, a dedicated backpack with a structured hip belt and load-bearing frame may be more appropriate.

How to use

Pack items through the oversized wide-mouth opening for straightforward loading and use internal mesh pockets to separate small items.

The included carry case can be used as an internal pouch for small accessories.

What to consider before purchase

• Intended use: choose this bag for travel, short trips, or weekend adventures rather than extended backpacking with heavy loads
• Carry preference: check that convertible duffel-to-backpack carry suits your typical transport needs
• Weather protection: suitable for weather-resistant performance but not fully waterproof in prolonged submersion
• Size: confirm the 40 L capacity and listed dimensions match your packing requirements

Usage recommendations

For best results, pack heavier items close to the padded bottom, secure loose gear with the compression straps, and stow the backpack straps when carrying as a duffel to avoid snagging. Clean and dry the bag after exposure to wet conditions to preserve the tarpaulin and recycled fabrics.
