grab it while it's on sale
Picked this jacket up on SAC for a great price and have been extremely satisfied since. This is my gf's new all-around jacket. It is exceptionally warm and has kept her warm to the single digits with only a light shirt underneath. Its gives a minimal "michelan man" look considering its has 650 down fill in it (though some bulk is expected given its fill). 5'4" and the small fits perfectly.
The jacket comes with a stuff sack, that when you stuff the jacket in, it stuffs down to about the size of 2 nalgenes. From there, you can easily stuff it down further, either with compression straps or simply just by stuffing it somewhere small in your pack. Dont' let the "size of 2 nalgenes" turn you off, this jacket gets much smaller than the stuff sack it comes in.
One of the best features is that the hood comes off. This is great for skiing so you don't have to stuff the head under your outer shell and look like the hunchback of notre dame (assuming you wear a helmet and are not using the hood). The internal pocket is nice if you don't want something to freeze. Another feature is that the jacket has thumb loops to put your thumbs through. This is not only good for keeping your hands warm but for layering and keeping the jacket arms in place.
The jacket also makes a dynamite tent pillow if you're not sleeping in it. On sale for $160 against the $230 sticker, you can't go wrong.
