Many here find it an excellent pack.
I have it and use ut occasionally.
It's got superb features for bushcrafting, is about the right size for your "big rucksack" and is about as hardwearing as they come. The fact that it can take PLCE pockets makes it even more versatile.
On a personal note though:
- I find it to have a bit too short back length, so if you're tall, it's probably going to feel too small/short for you (it doesn't have an adjustable back length and only comes in the one size).
- I find it too soft to carry heavy loads comfortably. And lets face it - with a big pack it will be for heavy loads.
If I were to buy a rucksack of this size and shape, I'd go for a Berghaus Vulcan.
- It doesn't have the PLCE pockets, true, but its own side pockets are made to be put together to make up a small daypack that works fairly well.
- It's also got a fixed back system, but unlike the Sabre it comes in several different sizes so you can find the right back length for you.
- It doesn't have any wand pockets, but I don't really miss them anyway.
- It's stiff enough to carry loads very comfortably. Believe me, I've carried much too much gear with this pack, and it's always been comfy to carry. Until my knees buckles from the weight alone that is...
I have the Berghaus Vulcan and have been using it hard for 12 years all through the year from deserts in Africa to snow in the north of Sweden and through forests and in the mountains in the centre of Europe.
If this is the size rucksack you're looking for and in the same prize range as the sabre, I can't recommend the Berghaus Vulcan highly enough.
