In reply to wannabeagoat:
I have one and think it's a great pack, especially for the money. Light, but very comfy even when packed with far to much kit. I spent six months with mine in Nepal and used it for everything from trekking, between lodges, day climbes, carrying heavy photography kit around and Island Peak. Back in the UK, I've used it for lightweight bivy trips and find I can get all my kit in, plus some camera kit quite happily. As with all kit through, your expectatiotions, needs may be slightly different from mine, so try it at home, if you don't think it's for you return it.
