Easy to handle backpack

Bought recently and have used for hiking twice . It's has got ample space to carry your stuff for 7-10days. High quality Sturdy made fabric and stitching is of top notch quality . Whats best is that it has got a twin side zipper in front of main cabinet . So it's easy to pull out things which are even in middle of the bag. One of the best bag in this category !!

Roomy durable and looks great

The TREK 100 EASYFIT 50 L BACKPACK is easy to use and fits to any body shape quickly and simply, the materials used are much higher quality than other comparable bags and it has a modern streamlined exterior to minimize snags catching on things during my trek. I prefer a single color in a backpack and i was glad to see that THE STRAPS ARE NOT ORANGE AS SHOWN in the pictures, only a loop at the end of a black strap is orange. Very happy with this purchase, seems larger than other 50 liter bags ive worn.. Decathlon youre awesome and im telling everyone who will listen

Not Comfortable

I used this bag with 12 kg of load for two days trek, but it doesn't feel comfortable on shoulders, natural curve on back is missing completely, balance of weight is not proper, it hurts your shoulders back. hence this bag is not at all good for trekking.


Hello Himayun

Thank you for taking out time to give your valuable review. We are sorry that you were not satisfied with the product. The issue you faced is normally when the load distribution in the backpack is not right or the shoulder straps and hip straps are not tightened properly which gives you a dynamic weight and eventually a pain in the shoulder or your back.

It might also be because of any defect in the particular product you are using. I suggest you to kindly visit your nearest Decathlon store and our Mountain sports team will be more than happy to check your product and provide you with the best possible solution so that you have better trekking experiences in future.

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
