Muppet Fur Fleece
Love this thing. Works great as a warm mid layer on icy cold days. Also great for cold days with no wind as an outer layer as it breathes really well. The slightly breeze blows right through it though.
I like how it looks (in orange) and and I get lots of compliments. People will also spontaneously pet you. This can be good or bad. It's mostly good.
THe only downside is that it doesn't pack down terribly well.
