Well in the search for lighter weight I fell for the charms of a new jacket and after much careful research I selected the Mountain Hardware Nitrous hooded jacket crafted out of 800 loft from some now rather cold or more likely dead goose. Ok, the careful research was a marketing email from Camp Saver offering a $239.85 jacket for $95.98 with postage being under $30 (all prices in USD). Heck I figured for under $140 AUD anything with feathers has to be a good buy let alone something with 800 loft goose feathers.
Well after a week the down completed it flight in the belly of a jet and arrived. The average weight was quoted at 401 grams but in the XXL with stuff bag this was 422 grams. Not bad for a hooded jacket. The fabric is light weight polyester similar to the WM Versa-lite sleeping bag. It is sown through quilted design. The more technical savvy of you would have done the mental sums and worked out it that is a delicate jacket with little fill so not going to be the Michelin Man look nor middle winter south pole wear.
It is designed for walking in freezing cold USA winters so should be ok for camp wear down to zero temperatures but I would pack my Mont jacket for colder mid winter conditions where the -5 happen. That jacket is 700 loft and Hydranaut material and weights around 750 grams in XXL fitting so the real deal. The 1kg MD in 650 loft and Repel I also have falls into, what was I thinking category, as I doubt it will ever be cold enough to wear that unless parked on a ski field all day timing runs in a lazy wind.
The quality of construction is faultless. In fact just soooo much better than another brand that I would never buy that had a recommend rip-off price of over the $600 mark. It has two side pockets and chest pocket all with zips and an inner large deep pocket without zip. The zips are first class and put my Kathmandu ones to shame. The hood is large and fits well but has no draw string so you cannot seal drafts off. This is the trade-off it makes to the gods of weight saving.
So for under $140 you get a top quality light weight jacket with a few trade-offs made to weight saving. Great for most of our temperate nights apart from the mid winter chillier season. If I had to have one down jacket it would be the Mont (Merlin?) but for $140 why not have two

Might even share it with a passing bear 
It was a punt that it would fit me but you have to admire the USA sites as they give pretty good sizing information unlike a well known local one that struggles with CM to MM confusion and arm length measurements
