Just received my SMALL Desna and it's a snug 2nd layer as I was after. I'm 5'10" with 36" inch chest and the dimensions in the sleeve are pretty spot on too.
The length seems a fraction though... it fits more like a pullover than a jacket and only just comes down past my hip bones (22" from shoulder to the bottom of the jacket). If I lift my arms I worry it will expose the guts a bit.
It's summer in Australia so haven't had a chance to see how well it works! I'm hoping its promise of some wind resistance holds up, as I don't want to have to take a soft shell as well as a Paclite shell when skitouring & snowcamping....
To be honest, however, it just feels like a regular fleece. It doesn't have the density of these heavy 'windfleeces' you see around and I'm not sure it would keep out more than a breeze.
But the hood does feel cozy under an outer shell...it'll save you trying to find a pocket for a beanie or a balaclava.
Looks great- just can't tell how warm it is. I just bought the North Face Valkyrie but realised when I got home the collar only comes under the chin. Why oh why!?
Has this got the same light fleece as the Valkyrie or less? And no underarm zips? Do they WANT us to buy three jackets? :-)
