Trekking Carry Bag - 40 L to 60 L - DUFFEL 500 EXTEND

The volume of each backpack is measured using a standard method: we use small balls to fill the main compartment as well as each pocket. We then we empty these balls into a graduated container which gives the equivalent volume in litres.

This bag is accepted as cabin baggage by most airlines. However, we recommend you check the authorised dimensions with your chosen airline.

This duffle bag comes with our “Extend” system so you can vary the bag\'s volume. It\'s a system of straps that free up extra space when loosened. Conversely, it also compresses the bag to reduce it to its minimum volume (40 L for this one).

Length: 55 cm Width: 40 cm Height: 32 cm (without the \"Extend system\")

We complete laboratory tests to certify components: fabrics, buckles, straps, foam, zips... for example, for a fabric: resistance to abrasion and tearing, colour-fastness in UV light, resistance to washing, waterproofing, etc. A test is then conducted on the finished product replicating the accelerated demands on the bag over the years to check the strength of the assembly.
