Good but broke after 2 years.

This bag was good for 2 years but the build quality is not great. we only use this bag on weekends away so it was not used often. The seams have started to wear on the sides. I would recommend spending a bit more and getting better quality.

I would not buy again

Very uncomfortable, achy back soon after having the backpack on. The shape of the back is square and large and it makes it very uncomfortable. Plastic wire was sticking out inside the bag and damaged my cardigan. There is no small pocket easy accessible for me but yet not accessible for thieves.
Overall i would have not buy it again

Poor quality materials - straps squeak in use and stiching already pulling out

For the price this has a lot of positives. The drybag is a good addition and the bag has a lot of straps to compact your gear when the bag isn't full. However the one I received had a broken buckle which makes me think the quality isn't that great but it was on the cheaper end of the scale for this size bag. The waist and shoulder straps can't be adjusted up or down so won't fit everyone. Best try it on to see if it fits you.

Purchased on sale- excellent backpack at the price. Construction and adjustability both seem good. Includes dry bag liner which integrates well within the backpack but can be removed.

I haven’t used the product yet but is perfect and exactly what I wanted. We are going backpacking for two weeks and it’s the perfect size for carryon on the plane. Impressed with the dry bag included and the extra side pockets, and water cover. I got it in the sale with 20% off which made it even better but to be honest I would have paid full price as it’s a good rucksack. Please I bought 2 one for the hubby too. Have recommended to our friends

Not a bad bit of kit

- Dry System works, A+
- Lots of pockets, easy to store and find stuff
- Good capacity

- No shaping/contouring at the back, designed for perfectly square torso?
- Shoulder straps not hugely comfortable, although if waist strap done up and weight settled there it does not matter
- Shoulder strap material squeaks a lot, not a dealbreaker
- No waist band pockets
- Only one lower pole/ice axe loop
- Adjustment straps rub on inner biceps

All in all an OK bag which I got on sale and am happy wearing for long-ish hikes. I would not have bought this full price as this is not a £70 bag.

New to hiking bags and this one seems a bit of a challenge. Took me 20 minutes to work out how to open the thing! Lots of Velcro, when I prefer zips, but it looks good quality and was worth the price.
