Up Jack

The missing layer

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. You'll know when it's time to grab a heavier layer, but for colder and rowdier conditions than you'd think, this over a base layer does the trick for miles. Really versatile wind jacket.

meets the purpose properly

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.

Versatile & Lite

This is a great layer for any occasion when it's not super cold out. Packs up great too. The fit is definitely for men. I usually wear a women's large but had to get a small in this and I still roll up the sleeves.
