Best puffy ever
I generally don't like puffies because they are bulky and I tend to overheat in them. This one is lightweight and just breathable enough to wear under any type of chilly conditions. When an arctic storm hit Lake Tahoe the temperature dropped to 5-10F, I just wore it over my longer underwear top and my shell for snowboarding and I was at a very comfortable temperature (I actually am a little cold usually and wear a thin fleece under my shell in 20-30F weather).
I actually wear it all the time now because it is so comfy. At my ski cabin, I wear it to bed because the house hasn't warmed up the first we are up (and head and shoulders are exposed above the blankets). I wear it at home when it is chilly in the late night and morning (thermostat is turned down 11PM-8AM to save energy).
