Excellent features Comfortable - Good weekender

The Easyfit adjustment system is a 'Gamechanger', so easy to get the pack to fit comfortably and this pack has so many sensible pockets, double zipped main compartment for easy access and all at a great price. Well done Team Decathlon - This is an excellent product.

Pretty good

I bought this for my son to use for his D of E trip and he said it was good except that it could do with two straps on the bottom to hold a tent or roll mate, apart from that excellent bit of kit and good value for money.

decathlon trek 100 rucksack

I didn't give it 5 stars as the main rucksack fabric looks cheap (I would rather pay a little more for better quality fabric!) and there were one or two loose stiches and its heavy for a 50 litre rucksack. Also the aluminium back stays are cheap .well that's the cons it only cost £49.98 plus it is a question of what do you expect .I like the fact it has the loops on each corner on the you could either attach some cord or straps to carry something that's potentially great and the shock cord on the hood of the rucksack. The bottle holder is another great idea .i would have been nice with a choice of colours .oh and the other plus the main compartment is divided so you get at your sleeping bag ,tent ? without tipping out everything so on the whole its a good rucksack (maybe very good for the price)

Not great functional

I used this bag with 16 kg of load for 3 days mountains baggies, but it doesn't feel really comfortable on shoulders, natural curve on back is missing completely, the ventilation is very poor, I got a massive wet at the back as no airway, balance of weight is not proper, it hurts my shoulders back. hence this bag is not at all good for long distance hiking or mountains baggie.

Fantastic Rucksack

A very versatile pack with a lot of features and a clever adjustment back system, quality at a low price if this was made by a big brand it would be over twice the price!

Great quality

This is very shallow but I was disappointed the rucksack didn't have orange straps like shown in the pictures. Fabric feels like excellent quality and I love the front access. Great product!

Well made rucksack

Perfect for day hikes, well made and well thought out. Plenty of well positioned pockets and a sturdy frame. Bargain fore the price.

Good rucksack

Very good rucksack. Unfortunately I had to return it as I have too much kit. Disappointed with it not being big enough as its good quality and exactly what I wanted.

Extremely happy with this

Great in quality

Absolutely free and comfortable to carry. Number of compartments helps in carrying multiple items and rain bag helps in emergence of rain.

Just Awsome

Using this bag in the Himalayan trek, Easy to use with an openable chain, Waterproofing is solid, checked with full snowfall not even a single item wet inside the beg. load-balancing is too good with carrying 11 kg of weight no back pain.

Worth The Price

The material looks very good. That adjustable thing works well and distributes weight properly.

Par Excellence

Grt quality, grt design, attractive looks, durable, overall good value for money.

Easyfit system

Our patented Easyfit system allows you to adjust the back height and strap tension simultaneously by pulling on one single strap (on each side). 1. Put on your bag2. Buckle and tighten the belt3. Pull the handles (from bottom to top)It’s adjusted!

Dying process

Textile dyeing requires a lot of water but also produces waste water from the dye baths.To reduce the environmental impact, we have opted for mass pigmentation (also called Dope Dye), integrating the colour pigments from initial thread manufacture. This process reduces this backpack’s CO2 emissions by 35% compared to the previous model.


50 L volume. The volume of each backpack is measured using a standardised method. we use small balls to fill the main compartment as well as each pocket. The balls are then emptied into a graduated container in order to determine the equivalent volume in litres, with a margin of error of just a few %.

How to pack a backpack?

Put your bedding at the bottom. Put heavy gear (tent, camp stove, food) near your back. Store your clothing around it. A groundsheet or tent can be placed under the flap or under the bag if there isn't room inside. Keep your waterproof jacket and fleece to hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. The water bladder can be placed in the compartment provided down the back.

Why are our rain covers grey when some trekkers want them to be brightly coloured?

The colour of our bag covers is neutral as it uses less dye. We also use a “bi-ton” dyeing process where only one thread in every two is dyed. This dyed yarn is also made from a bulk dyeing process which incorporates the colour pigments from the yarn manufacturing phase onwards. Forclaz is committed to improving the environmental impact of its products through these actions.
