I have had this rucksack for 3 years and I have used it for hundreds of hiking, mountaineering and climbing trips. It has always been up to the job, however, on especially long days, the shoulder straps start to dig in and have left me marked for days. Having one Ice Axe loop and holder isn't great, however I generally use the side compression straps but I'd rather not.
The toggle on the lid can be a faff but it does allow for a huge amount of extra storage, for a rope or helmet in particular. The chest strap catches on either side of the shoulder straps do have a tendency to ping off from time to time but are easily replaced or put back.
On the plus sides, the side access is handy, the internal zipped pocket on the side entry, the external front pocket, the external lid pocket and internal lid pocket with key holder are great features. The rain cover has never let me down and I've always been able to fit in all my gear with ease, and I bring a lot of gear.
In short, its good but not great.
