Wife is Happy

This was a purely speculative purchase for my wife for Christmas. She likes it a lot, and will keep it. Sorry, I can't give any feedback on what it's like during actual outdoor activity yet.
It seems very well designed and put together. I like that the material has a little more "heft" than simple fleece, and at the same time isn't bulky.

Most awesome sweater

I love this sweater. It has just the right amount of insulation and it is so soft. I am 5'7", 125 lbs, slim build and the medium fits very well. Large enough to fit a baselayer underneath and not baggy at all. If it wasn't for the price, I would have 2 of them.
