I've had one of these for the last couple of years. I use it for overnighters and chasing tahr. Great pack, the only fault is the mesh pockets on the side are a bit fragile. I've ripped mine to bits scrambling around rock etc. otherwise they are bulletproof.
I've also got a cactus huntaway which is also a good pack but slightly smaller and I prefer the k2 which is a bit more comfortable on the shoulders.
Cheers
