Good Design... Good Fit.. but...
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.
