I was looking at a Hyperlight Mountain Gear pack, but getting here from the States, given exchange rates and shipping, was going to cost $650.
So instead, I've ordered one highly recommended by one of the regulars here, Gaiters.
He recommended the Exped Lightning. A 60L roll-top pack with unique suspension system, it weighs just 1.1kg.
It hasn't arrived yet, but I'm excited to get this pack! And given that Bivouac currently have a 20% off everything sale, it only cost me $280. Bargain!!
@phil21 I own a Zpacks Arc Blast. I really like it, but it is a pack made for a specific type of activity. For example, they are not designed to carry more than 15kgs with any regularity. The frame is also somewhat delicate. The fabric is also not designed to be sat on or thrown down a scree slope, but it is surprisingly durable given what it is. Mine has survived severable very rough bush-bashes. The only other thing to know is that their listed volume is not just the interior volume, but includes the back mesh stuff pocket (8L) and the two side pockets (1L each), so their 60L pack only has a interior volume of 50L. That being said, if you need 60L worth of space you're probably carrying too much to comfortably use an ultralight pack. Ultralight packs are for lightweight loads.
I'm a fan of the Osprey Exos 58. I have the large, which in effect is 61 litres and it weighs 1200g.
A great harness and good for up to 15kgs.
We have two of them in the house, so the go-to pack for 2-4 day outings.
I should mention I had an Arc Blast 60 but found it too 'delicate' as mentioned above. Sold it.
