In reply to John Mcshea:
I got a Mammut "something" click harness, the ones with the click together leg and waist loops. It's pretty comfy but then i'm only comparing it to a single gear loop webbing harness which I'd used for 4 years or so and was pretty uncomfortable. Can't really fault the construction, the click together thing is great although I'd rather the buckles were all metal as I nearly wrote the harness off by slamming it in the car door once.
Arcteryx do get a lot of good reviews on their harnesses, I guess the best bet would be to sit in a couple and see which fits you best, depends how long you're going to be sat in it i suppose.
