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.

Best rucksack you can find

ขนาดถือว่าเหมาะสมกับคนที่สูงประมาน173ครับ ปรับกระเป๋าง่ายกว่าตัว4000 แต่ข้อเสียที่เหมือนกันก็คือ สายกระเป๋าไม่นุ่ม เดินนานๆรู้สึกว่าสายสะพานบาดคอ ต้องหาอะไรมารองคอทุกครั้ง

Bag quality doesn't seem to be good

I have used it for my first trek and the stitching isn't that great and the bag threads are wearing out and the bag also got damaged very easily... it's not worth the price i have paid for this trek bag.. find very expensive for that quality...

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!

The zipper in the front is very useful.

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.

Product is good overall

overall, product is good, good make and posture, easy fit for any type of hiking/trekking. Only thing I feel lacking is place to fit sleeping bag on top of the bag. it has strings on top to fit but for small things like normal jacket, not for sleeping bag.

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 straps (from top to bottom)You're ready to go!

How to pack a backpack?

Put your bedding at the bottom. Near your back, place heavy equipment (tent, stove, food). Pack your clothes around these items. A ground sheet or tent mat can be placed under the flap or the bag (add straps) if they cannot be fitted inside. Keep a waterproof jacket and fleece to hand. In the pockets, place small items for the day (sunscreen, map, glasses...). The water bladder can be placed in the compartment generally provided down the back

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

The grey colour is neutral and therefore uses less dye.The component is made of BITON: this process allows us to lower our CO2 impact and reduce consumption and water pollution in comparison to coloured models.These small measures demonstrate the commitment of Forclaz to improve the environmental impact of its products.

10-year warranty

Our engineers have conducted tests simulating the ageing of rucksacks. These tests are conducted on the components, seams and finished product. The results enable Forclaz to guarantee the tested bags for 10 years from the purchase date shown on the receipt
