There's the Golite Jam at under 1kg, you should easily be able to pick up one for less than £100 S/H, but i think they are 50lt, frameless too so not everyone gets on with them, i found it crippling to wear with any weight in it but others swear by them, they come in different back lengths too so be sure to look out for that also.
Can't think of any other load luggers that come in under 1kg off hand.

Just found the OMM Mountain mover too, seems you can "tailor" the weight between 1.6kg/600gr @ 55lt + 15lt.
Whilst i endevour to keep things as light as possible i do insist on a a good back system so totally ignore these type of packs, others here will be able to offer you a wealth of advice in actually using them that i can't.
Welcome to OM btw.
The Pinnacle has reverted to being the Jam 70 and is probably only now at ultralight outdoors gear (here.). Well maybe some spare stock elsewhere but the rest of their UK distribution is gone.
I would try and be realistic about how much weight you're going to be carrying though - pack frames do help with big loads and you can still get pretty light packs with some sort of frame system. 1.5kg will give you reasonable leeway, and even 2kg might not be a crazy percentage of your overall load.
Certainly try anything you're thinking of with a load in it in advance of setting off! Pack comfort is quite an individual thing.
Looks like the Golite Pinnacle has now been replaced with a 70L version of the Golite Jam. 60L, 1kg and under £100....Would be good to know the estimated weight of your pack. If its anything like 20kg it might be worth considering a framed pack in which case 1kg might be impossible. Sounds like you are new to this and comfort is a big deal (for me anyway) when it comes to multiday trips....Even if you can find a pack that meets your specifications, you probably won't be able to try before you buy, which could be a really good idea!
Since we are talking lightweight large capacity backpacks on this thread I thought I would hijack this a little and ask what the best frame backpack for loads up to 22kg might be? At the moment I have and Osprey Aether but I have been considering a Golite Quest (1.5kg) to save 800g.
Whatever lets you stand up and move reasonably comfortably I'd say
At that sort of load surely rational to be trying to cut the load down before the rucksack?
The quest looks a good option, but I have had no problems with my Pinnacle. The weight difference is about 600g (the Pinnacle is lighter). To shave 600g off a tent or sleeping bag is costly. I think that the cheapest form of saving weight in general tends to be rucksack.
Well the very cheapest is leaving stuff behind
The issue with rucksacks is that carry comfort genuinely is the important thing, over and above most other things. Now with smaller loads there's much more leeway to mantain that.
But with big loads - like the 22kg one above say - a badly fitting rucksack will be very uncomfortable or even simply plain unsuable for any length of time. In fact for that sort of load I'd say that even +-1kg rucksack weight isn't terribly relevant, so long that is as are you're getting carry comfort for the weight!
(and not pointless 'features' etc.).
That latter is of course very far from guaranteed and certainly no reason not to try lighterweight things. I wouldn't call it a priority though.
as martin says it's all about comfort.
you can carry 9kg like it isn't there and you can carry 9kg in hell. a proper back and carry system more than repays any weight difference between packs.
Pile up what you've got and see what it roughly takes for size Quoted rucksack sizes actually far from standardised so it might be another thing you have to check.
I'd also concur with being a tiny bit unsure if you'll hit 9kg. 10/11 seems more likely but thats obviously still entirely managable.
If you are looking at the Golite rucksacks second hand don't forget there are different back lengths used to be three with the Gust think there are only two now with the later models.I have a couple of Gusts but they are short backlength as I am only 5'6''.Only weigh 19oz I fitted them with 1'' foam instead of the 1/4'' foam backpad to stiffen the rucksack
