Perfect layer for huffing and puffing. Cuts the wind, sheds light snow and gives the comforting illusion of shelter in steady precipitation. The anorak/poncho design takes me right back to the cotton drug rug throw overs we used to buy in Mexico. And it breathes! No swamping out.

I've been wearing Up Jack on a thick undershirt while hiking up in winter Hokkaido, Japan, and it keeps not being too hot nor too cold, as TREW mentioned. The large kangaroo pocket sometimes stores blown snow, but it doesn't causes any problems so far.
