Sabre 45

[twentyclicks]

I can second the others that the Sabre 45 is bombproof.  Mine has been bashed through forests, rocks and ice and still looks new.  I've had 30Kg in it and it was me that broke 

It's not very 'mountaineery', but I love the side pockets for storing gear orderly and having it accessible.
I've never been entirely happy with the fit of mine once I started using it - so would advise you to try on somewhere that has the different sizes as they are non-adjustable.

2 points against it:

• Durability comes at a cost - it is heavy.  With the side pockets it is about 3Kg!
• The top of the bag is narrower than the bottom which makes getting things in and out a bit annoying.

I use mine now for day hikes, or putting weights in for training, but have a Granite Gear for longer trips as it is half the weight.
