Men's mountain trekking rucksack | TREK 500 70+10L - olive

Large rucksack for DoE & general use

I bought this recently for my daughter to start using for Duke of Edinburgh activities but also to use myself longer term for general use and as a large rucksack for travelling. As she is 5'4" and I'm 5'11" it needed lots of adjustment to fit both comfortably and lots of practical design features to work for both needs. We tried different rucksacks from much cheaper to much more expensive and this was the clear winner on design & features.

Great wild camping bag

Bought for wild camping. Fitted loads of things in bag thanks to front, bottom and top openings as will as outside pockets, straps looked small but were fine with heavy load. Adjustable back to fit size of body and room for a water pack inside bag. Could also attach walking poles and tent to outside of bag. Really please with first use just need to adjust it properly to suit my size.

Trek 700 Rucksack

I am really impressed with the build quality of this rucksack it is exceptionally well made and will be perfect for what I have bought it for and a great price

Good Buy, Little Expensive, But Quality Is Awesome

Products fabric, stitching, finish, styling and color are too good. Usable for 15 days plus trekk. Can be used for casual travelling. Carry comfort is also nice. Back suppot is sturdy and wight proportion is awesome. Nice product. You can buy, although it's at little expensive but Five star for quality.

Quality is Excellent but The Bag Weight is 2 kg em

If you think to hiking with this Bag then its already 2 kg empty bag . So you can't tak any good coz There already 2 kg extra.

Amazing bag for Several days trek

Loved the way the bag is designed, the bottle holder near waist to grab bottle on the trek. Dedicated water bladder compartment to stay hydrated. Padded net on the back for comfort and alignment of back on to back. Overall loved the bag and Olive color is so perfect for adventures and loving this bag. Thank you Decathlon for the wonderful product :)

Excellent backpack

I recently completed my Annapurna Circuit trek with this backpack. Excellent bagpack

Super comfort

Awesome product. Bought it in Bucharest, Romania for few extra bucks but no regrets.

It's a great backpack . Purchased it last week.

Absolutely perfect for long treks

Very comfortabl rucksack...

This one is the best product amongst all the backpack of this size in decathlon, shoulder straps are very comfortable gives you very good feel when you wear it and i recommend this type of bags over symbium style... Pros:raincover(grey color), very comfortable, 1bottle holder, light weight in comparison to symbium Cons: first of all the colors are not so attractive i must say and the two most important thing for me are... 1.No ice axe holder loops and 2.No over the lid strechable straps are provided to attach crampons etc which is very useful But this things can be done on extra cost if you really need all things on this backpack stitch it from local bag Tailors as i need to do.. Overall this backpack is worth to buy it is perfect for trekkers just go for it.... Advice to Forclaz is that provide ice axe loops and crampons strechable straps over the lid compartment with all of your products specially this trek 700 series as these are high budget bags and should include all needed loops and straps.. And please change the color if possible make it dark grey or black... This bag have all the potential to rock the market of rucksack but only if forclaz do some necessary improvement... Thankyou

Extendable volume:70L + 10 litres extra thanks to the adjustable height of the bag top.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. 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. Pack your clothes around these items. and the tent beneath the pack if there is no space inside. Keep a rainproof jacket and fleece close at hand. Keep a rainproof jacket and fleece close at hand. Place small items for daily use (sun cream, map, glasses etc.) in the pockets. If carrying a hydration pack (water bladder), this should be placed in its special pocket along the back.

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

The grey colour used for the covers of our trekking rucksacks is neutral because it consumes 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 guarantee

Our engineers have carried out simulated ageing tests on these backpacks.The tests focused on components, seams and the end product. The results enable Forclaz to guarantee the tested bags for 10 years from the purchase date shown on the receipt
