Familiarity: I've used it several times
Lightweight enough to forget it's on, compressible enough to store it in one of the smaller pockets of your pack, and warm enough to keep you toasty on a good hike or a cross-country ski in the dead of winter. Layers perfectly with hard shell for cold rainy days. To top it all off, it's on sale. If you want a mid weight synthetic that'll look good on you, stop looking and buy it.
