Well we are home now, after out overnight camping adventure in the Naas Valley and walking up to the Horse Gully Hut. Overall it was roughly 20kms round trip.
I weighted my pack when we got home and it came in at 10.7kgs with 900g still in my water bladder.. I can assure you that is rather a load when you are climbing up hill and down dale.
Have a watch and tell me what you think.
