Questions & Answers

Look for product information, frequently asked questions, opinions...


Do extreme temperatures, like being stored in an attic, effect the texture of the bag or cause it to feel sticky?


The prioduct should be stored in dry and moderate temperature. So far, we did not receive such feedbacks regarding any sticky aspect.

Very well designed bag.…

Very well designed bag. Modular according to capacity. Protects things well. The different portage points are practical.

Very good duffle bag, but could be improved

I've been using this bag for almost three years, and it has now become my main luggage for trips of +/- 1 week. Here's my feedback in broad terms: Capacity: it's impeccable for me. 40L expandable to 60L covers almost all my needs. Compartmentalization: there are no miracles; apart from two small interior pockets on the ends and a small exterior pocket for quick access you will only have the large main pocket for your belongings, but that's what makes this type of bag interesting in my opinion . Personally, I recommend using this bag with additional compression bags: it's much more modular and allows the bag to maintain a nice shape when full. Resistance: the canvas of the bag is super thick, and the seams are clean. By having the luxury of being quasi-waterproof, the bag seems to be virtually puncture-proof. Very good when loaded in the back of a vehicle Look/Design: that's where the problem lies, unfortunately. In terms of RAS look: it doesn't have to be ashamed of models found in other brands by affording the luxury of being less expensive. On the other hand, in terms of design, I am a little disappointed with the choices regarding ergonomics when transporting by hand. The straps of the bag are quite thin, which might bother some people, but you can get used to it. The chest strap is not installed on a rail, like on other bags, but sewn around a fabric strap attached to the shoulder straps. This somewhat limits the possibilities for adjusting the chest strap in terms of height. The side handles of the bag are super nice for carrying the bag in Duffel mode, and the flaps at the ends do the job for compressing the luggage. On the other hand, a big blow: there is no waist belt to unload the weight of the bag from the shoulders. This seriously limits its ergonomics and the duration over which you can carry this bag. What I don't understand is that another model in the same range (Duffel Extend 900 WP) has loops to attach a waist belt. It would have really been great to have the same system on this bag. Small aside: you have to take what I'm about to say with a grain of salt, but I think it would be possible to have a reversible waist belt system on this model without even having to change the current design. On either side of the side handles there are fairly thick ribbon loops, and I could well imagine a waist belt that would attach to the sides in said loops. In conclusion: the bag is well designed as a duffel bag, it is very robust and has good ideas, but it would have been cool to have more features for use as a backpack. Otherwise, I recommend ;-)

For the price this is the best duffle bag

duffle bag excellent value for money. "compression" system to reduce the volume really not so bad... Perhaps less stylish than premium brands but it more than does the job

Travel bag and backpack in one

Bought for my husband as a Christmas present. He needed a travel bag and a backpack. This was a great 2v1 choice!!. It can be worn on the back or over the shoulder. Quality material, stylish design.

Ultra practical

Admittedly, I use the bag less for trekking and more simply as a practical packing bag in the car/caravan. The part is great.

Solid and well designed

I recently bought this bag after comparing it for a long time with other brands because I wanted to find a product that would perfectly protect my belongings from bad weather with a beautiful design and practical storage. With its handles on all sides and its ability to expand I can really carry a lot of things and the carrying straps don't hurt even if more padding would perhaps be more suitable given the portable volume. The zippers are sturdy and very large, which I appreciate, whereas other bags tend to have small ones. A real adventure bag I think!

“extend” system

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).

Hand luggage

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

How is bag volume measured?

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.

Technical tests

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.

Product testing

Here at DECATHLON, our products are tested by a panel of users in the real-life conditions for which they were designed. At FORCLAZ, these tests are organised on the mountains, led by a team of engineers from our design centre, who are responsible for this mission.Our product managers, engineers and the entire team use the results of these tests to develop and create technical products to ensure the satisfaction of our customers
