They're okay, but you get what you pay for. I have a 5 year old Vango that i have repaired and now use as my cragging sack. They aren't as comfortable as an expensive bag, aren't as strong and aren't as user friendly. But they are cheap.
It depends if you are looking for a bag for occasional use or about to do the GR12 or something....
