Product Customer Reviews
The backpack is spacious, it's nice that it has more pockets
The strap that secures the line on the outside should be a bit more solid and thicker. That's the only criticism I have about this backpack, apart from that it's a great design!
This bag is awesome. You can feel the quality despite the lightness. I've had it for over a year and it follows me everywhere, to work for jacket + lunchbox, mountain biking (the helmet pocket is very practical), day hikes, via ferrata etc... If it had had slanted doors it would have been the definition of perfection with a beige color perhaps.
Perfect for extreme sports
I used it with the weight one normally carries for long routes (gear and rope), and it hurt near my armpits, so I think they skimped a lot on the material in that area. The Velcro also wears out very quickly.
I use it for everyday use because of its comfort. I even walked the Camino de Santiago from Tui with it on me at all times (it did bother me in the last stages because of the handles), but otherwise it's totally recommendable.
Well thought out design.
Lightness, versatility and comfort achieved
I use this backpack for long routes. I like the sack-like design that gives you a lot of security when opening it at belays, and the fabric is durable.
Very good climbing backpack. You won't find anything better for this price. It is very light, can be rolled up. Resistant to abrasion. Does not restrict movement during climbing, which I consider a huge plus. The hip belt is set high enough, because it did not interfere with access to the harness. Not suitable for trekking - it is not designed for that.
Very light backpack, good and cheap for what it's worth.
The bag is great, but I can't find the helmet net: do I have to buy it separately?
The material is too thin and poorly reinforced. We used it on our first morning climb, and the fabric already has a hole.
Ideal size for day trips. Fits very well.
A very lightweight backpack with the essentials for your long-distance climbs and via ferratas. It's comfortable and fits everything you need.
