Value for money

Amazing value for money. I’m so pleased with this backpack. Originally was looking to buy more expensive brand that would cost me £120 but this backpack has everything I need for a hiking day trip. Opening from the top as well as side zip which is handy for quick access. Waste side pockets are great. Can be used for a mobile phone or high energy snacks so you don’t have to stop to find it inside the bag. I didn’t understand the angular drinks side pocket at first but when I started to use it it makes perfect sense. Again, you can access your drink without stopping to get a drink. For those who like a water bladder there’s a space for it inside. Hiking pole straps are strong and hold both poles easily. Chest strap can move up and down depending on your comfort. The only disappointing feature this backpack is that is missing is a whistle at the chest strap (unless I’m blind). Don’t think I would get this backpack if I hadn’t seen it in a shop and tried it on. Make sure you buy the right size as they do small and large depending on your height!

Great design

Have now walked 100+ miles with this backpack. Hip belt keeps weight off shoulders; and the side zip is great for getting at an item without having to unload everything. I particularly appreciated the fact I could get a back designed for a taller woman with narrow shoulders. So pleased with it.

5 star backpack

Excellent quality. Very comfortable and plenty of room to store everything you need for day hiking. Love all the clever little details too - like the easy access bottle pocket and the thumb loops on the shoulder straps.

Commuting Rucksack!

Use this as my daily commute run bag - adjustable so running is comfortable more than enough space for essentials. Good range of pockets for everything, laptop, drinks bottle, gloves, sunglasses. Also nice pockets at front handy for phone and wallet.

Fair price, not overwhelmed with quality

I purchased on recommendations that the MH500 had good reviews and my general faith in Decathlon goods. Arrived well, nice looking bag. Unsure on how long the plastic clips will last, but they seem to be the going standard. Has an odd system for opening the sack...why not just us a typical type of toggle? One of the zips on the interior has been installed backwards also, meaning I can't really get into that pocket. I'm sure the bag will last, so it's not worth the hassle of a return, but I do wish I had spent a bit extra for a 20l bag.

Great buy

excellent quality rucksack with extra features that you usually only find on rucksacks double the price. Highly recommend

Great value rucksack

This is an excellent sac, it sits comfortably off your back and has great features of a much more expensive sac. I love the hip pockets and the side zip options. Practical and useful. I bought one in France and now have one in the UK

great day pack!

got this pack for Christmas and have put about 100km on it in the last few weeks. From Provincial trails to Back woods orienteering. This pack has been comfortable and sturdy. the added rain cover has been super handy as here on the East Coast of Canada we can have all 4 sessions in a matter of hours.

I use it for biking

Light and lots of space. Feel comfortable carrying it biking a whole day.

We take care over abrasion resistance to make your bag durable.The heavy clothing R&D department, a Quechua partner for the research and validation of its components and assemblies, performs tests (on components, seams and the finished product) simulating the ageing of backpacks.Their results allow us to guarantee the bags tested for 10 years from the purchase date shown on the receipt.

Don't throw it, fix it!

Our products will join you on your mountain walks.As you progress, they age, and some parts can get worn or break.To make repairs easier, in the "Bag accessories / hiking trekking", we sell tightening buckles and chest clips that are compatible with your bag. Don't throw away, repair !

What differences are there with the old mh500 bag?

The back of this new bag has been fully reworked for greater comfort: a tight net with frame gives you more space between your back and the bag to reduce the damp back effect. This net used for the back, called mesh, is also softer than previously. What's more, this new model comes in 2 sizes for small and large sizes.The 2 hip pockets are more spacious and stretchy and access to flask on the sides is easier.

Which size should i choose?

During several field test sessions with hikers of different sizes, we noticed that between 20 and 40 litres, the difference in comfort was mainly down to the back height of the bag. We therefore offer all our models in 2 sizes to meet these requirements. If you are taller than 170 cm, go for size L. If you are shorter than 170 cm, you will be better off with a size S.


This bag can hold 1 litre, 2 litre or 3 litre pockets. However, although the pocket is voluminous, it will take up place that could be used for storing other belongings.The side pockets are designed for flasks of maximum 1 litre.

Why are our rain covers orange?

This is a deliberate choice as we believe it's important to stay visible in the mountains, even in fog, in case of any problem. This orange colour has the advantage of being visible from a helicopter.It's also a visible colour on the road if you use your bag when cycling.

Hand luggage

When you are travelling by plane, the authorised hand luggage size is 55x35x25cm3 maximum (warning, this can vary depending on the airline).This bag can be used as hand luggage, so long as you don't load the top too much.

How do i adjust my backpack?

1 - Loosen all the straps (straps, hip belt, load adjuster straps). 2 - Put the backpack on.3 - As this bag is small in volume, put the belt around the waist and tighten it.4 -Tighten the shoulder straps.5 - Adjust the load adjuster straps as needed.

How to pack my backpack?

AT THE BOTTOM of the bag, pack your sleeping material, and heavy material nearer the back. Slide your water pocket into the compartment.AT THE TOP of the bag, store your waterproof jacket and fleece within arm’s reach.In the pockets, you can put your sun cream, maps, cap and sunglasses. Cereal bars or your mobile phone can be stored in the belt pockets for quick access.The straps under the bag can also be used to attach a compact tent.

How to care for and wash a rucksack?

We recommend hand-washing your rucksack. Use soapy, lukewarm water, possibly with a brush, focusing on the areas in contact with the body (shoulder straps, back, waist belt), where you have perspired.This is the best way for the fabric properties to be maintained, in particular the waterproofness.Then rinse well with lukewarm water, dry in a dry place away from direct sunlight (no radiator). Store in a dry place.
