/ Super packable Primaloft top.
Probably going to be 60g all over rather than 100g.
I have one and use it as a mid layer and on its own, brilliant bit of kit.
Also the arcteryx lt jacket is another perfect pice of kit, Well made, functional, looks great .
Both with 60g Filling, coreloft is worth considering .
But for light weight and packable the nano wins IMO.

Rab Generator. Okay, it's 100g in the body, not 60, but it's still super packable and very warm. And I mean VERY.
I use a Rav xenon. Brilliant jacket. Packs into its pocket and has a hood. It's been pretty hard wearing too really, for the thickness of material.
I means "rab!" Damn auto correct!
I have one of these and rate it
+ 2, I haven't worn mine yet but my friend's is very nice :)
Thanks for all the suggestions. The idea is as an emergency layer whilst out running in the hills. Not worried about carrying an extra 300g or so. Will look at the suggestions.
The idea of the Patagonia Nano puff is good, but they have made a couple of design errors which make it a pain.
1.) The cut is far too square (unless your a porker) - result is lots of dead space and a poor fit.
2.) Hood is too small to go over a helmet.
Arteyrx Atom Lt (60g Coreloft) is a much better design. The fit is excellent and as a result the warmth to weight is much better.
I totally agree.
Primaloft 1 or Primaloft Sport
All the major brands have Primaloft jackets.
Arc'teryx use http://coreloft.com/
And now Polartec are launching Alpha.
How do you find the cut? I had one for ages but I found the cut really square, there was a ton of spare fabric round the front.
Also - the hood, how do you find it? I can only just squeeze the hood over a Meteor helmet which I find restrictive.
I suppose it depends on your shape really.
Another vote for the Atom LT - I have the hooded jacket which is a nice trim fit with no excess material at the waist. Like others, I tried the Patagonia Nano Puff but found it wasn't that warm as there's far too much flappy material around the midriff - if you got it taken in by a tailor, it would probably be spot on.
The pack size is tiny and its very adaptable, in the summer i take it clipped to my harness on alpine rock for chilly belays but have also taken it as my warmest layer for 1000m northfaces this time of year and wear it combined with a base layer and shell for winter stuff (with a down jacket for belays).
+1 for nano-puff, my most often used sythnetic insulation.
However I also agree with the comments about boxy design. I have used it over other layers and this has been useful at times. The neck however need a cinch cord to seal better.
If I lost mine I would buy similar with a hood, and defo look at Atom LT; I have other Arcteryx jackets and the hood design and size is the best I've found - plus general design excellence.
Yeah, I have to admit I'm 6ft but only 65kg - which probably accentuates the fit problem. I also notice the arms are a bit short - especially when you're working with holds / tools over your head.
Yep I agree, the pack size and adaptability are great. I used mine in almost exactly the same way.

~300g Elasticated stitching stretches over other layers and eliminates dead space, helmet compatible hood. Not available outside North America though :(

Just looked at the Shipping conditions - they do ship internationally for $50. So you can get them if your prepared to wait.
I had an sv in small and loved the jacket in every way but the fit round the midrift,it was just way to baggy under a harness much more of a snowboard jacket fit than a trim alpine type fit,i sold it and bought a second hand nano puff hoody,this fits much better under a harness but in every other way the atom sv is better !.
i would be interested to know if the lt is actually a slimmer fit,but the lt dosent have a volume adjustable hood which i think is a letdown.
Another vote for the Rab Generator from me, superb bit of kit & very toasty
Cliff - yes the Atom Lt is a much slimmer cut than the SV. Try one for size.
I'm 6ft and slim (65kg) and the medium fits perfectly. My old Nano Puff was like a sack on me in medium.
