Duffel bag Thule 5590 Chasm 40L — 40 L capacity, darkest blue

The Thule 5590 Chasm 40L duffel bag in darkest blue is a 40‑liter travel and outdoor bag designed for versatile carry and durable protection of your gear. Constructed from weather‑resistant tarpaulin fabric and 100% recycled exterior and interior textiles, this model combines durability with sustainable materials. The oversized wide‑mouth opening gives straightforward access to the main compartment, while internal mesh pockets and a included carry case keep smaller items organized.

Advantages

The bag converts from a duffel to a backpack with tuckaway shoulder straps for flexible carry options. Reinforced oversized grab handles and a padded bottom ease lifting and protect items from rough surfaces. External compression straps stabilize contents in backpack mode and the large zippered mesh pocket offers quick access to essentials. Lockable zipper pulls provide a theft‑deterrent option (locks sold separately), and the use of recycled fabrics supports reduced environmental impact.

Suitable for

• Weekend trips and short travel
• Gym and sports equipment transport
• Outdoor activities where weather resistance is needed
• Commuting with variable carry preferences (duffel or backpack)

How to use

Open the oversized wide‑mouth zipper to pack clothing and gear into the main compartment. Use the internal mesh pockets and the included carry case to separate small items and accessories. For hands‑free transport, pull out the backpack straps and secure them; when you prefer duffel carry, tuck the shoulder straps into their compartment. Use the external compression straps to stabilize the load and protect items with the padded bottom when setting the bag down.

Usage recommendations

For best performance, close the zippers and secure the compression straps before transport to minimize shifting. Use lockable zipper pulls where security is a concern, and store the included carry case inside the main compartment to prevent loss. Clean the tarpaulin exterior with a damp cloth and allow to dry fully before packing to maintain weather resistance.
