Sierra Designs Flex Jacket

[ljcsov]

Hey all,

I am looking to get my first down jacket. I have plenty of fleece gear but wanted to pick up something that is pretty compressible and extra warm. Does anyone have experience with the Sierra Designs Flex Jacket?

Other jackets I have checked out...
Eddie Bauer First Ascent Downlight Sweater
Marmot Zeus
Moosejaw brand down jackets
MountainHardwear Nitrous
Patagonia Nanopuff

Any help would be appreciated
