Not heard of this brand before, it's mainly for adventure racing. Name of the pack is 45l Ultralight Pack, but ironically no weight is mentioned in the specs (or I'm just missing it).

From the specs and appearance (plus the reticence about specifying the weight despite the 'ultralight' claim), I would doubt if this comes in at much under 1500g.
We might play an amusing 'Guess the Weight' game until we can get it verified?
I'll go 1465g
