I bought this backpack to use as my day pack on the Everest Base Camp trek. It carried all I needed for the day, waterproof, fleece, camera, down jacket etc. The side pockets for water are more spacious than they seem, a Nalgene bottle fits in them. The waist band pockets are ideal for lip balm, sun cream and any little bits and pieces. The zipped pocket in the top flap is incredibly useful. It felt comfortable on my back, I had no issues with any aches and pains, adjustment is easy and the shoulder straps are perfectly designed. Yes, my back got sweaty but the ventilation soon got rid of any moisture. The waterproof cover in the base is good, only issue is that it's attached so if it gets wet, it's awkward to dry but a pair of scissors sorted the problem and the cover can be hung up separately now. High quality and equal to Osprey products and at a much better price.

I’ve used a plethora of bergens/rucksacks over the years on military ops and latterly as a keen hiker. I went for the 30 litre version and used and abused the bag during the build up training and completion of Everest base camp last December. It behaved superbly and put up with everything thrown at it including winter Brecon and the Himalayas. A lot of thought has gone into its design and functionality but the clever angles of the water bottle carriers work extremely well. I use both the bladder and bottle. On the move using the bottle was a doddle instead of faffing about trying to reach it. The back airflow system also works a treat which helps to stop a soaking, sweaty back. A 2 litre bladder sits properly and tucks away nicely. Overall and for the money, a diamond in the rough. Great job.

Great size very comfortable this is a very well thought out piece of kit but please try before you buy in the shop like I did I spent a good half an hour in store going through sizes and features this can easily take my waterproofs both tops and bottoms my lunch first aid kit hats and gloves etc a pocket for maps two hip pockets two water bottle pockets one side pocket a place for walking poles and a easy access zipp so you can grab gear from the bottom of your pack as well as a built in waterproof cover I did compare this with the thirty litre version but I decided this is more practical because of the extra ten liters the 30 ltr was just two small in my opinion

This rucksack has a really well designed frame, back system and hip belt and is a very comfortable all day carry. It is reasonably light in itself but this is less important with rucksacks than how they transfer their fully loaded weight to your body and this one is excellent at that. It has an adequate air gap for your back but with a less pronounced curve holding it away from your body than a lot of rucksacks which helps both the load transfer through the shoulders and stability. It also means the main compartment remains a nice regular boxy shape and easy to fit your kit in. The straps are easy to adjust for a good fit and don't slip. The main fabric seems quite tough and durable but the stretchy material used on some of the external pockets whilst saving weight and working well have scuffed up in one place after a bit of bushwacking. The pockets I find most useful are the top lid pocket which is really big, the large stretchy front pocket and the zipped ones on the hip belt. The slanty side water bottle pockets don't seem very secure but I can manage without them. The compression straps on the side work well and double up for carrying a sleeping mat. Sizewise it is has a noticeably bigger capacity than my 35litre rucksack, doesn't seem to hold any less than my 45litre but is a nicer more compact shape. Almost tardis like.

Good comfort and good value for money.

The product is basic, but so is the price, so no surprises. It's a good bag, which won't last for years, but I enjoy using it for day hikes.

You need a 40L bag, just go for it!

Very practical. I carry my training stuff in it and it can also hold a small purchase of food/drinks.

Lack of pockets compared to our old Decathlon backpack

Corresponds to the description, practical to use, I recommend.

Excellent for hiking or as a travel bag
