full coverage lightweight winter wind jacket
I primarily use this jacket for frosty morning runs in the winter. It's also nice for x-c skiing. I like starting and stopping with the hood. With a mid-weight layer and base layer vest (CW-X) underneath. I run comfortably down to 0 degrees and 10 mph wind. It's nice to start with the hood and take it off if I get warm enough during the run and the thumbholes seals and covers the wrists. The color I have also has nice visibility.

pretty good
The Jacket is alright for cold weather. It will keep you warm as long as you don't stop moving. It is extremely lightweight. It has an athletic fit,I love it.

So great jacket for riding
A few months ago I heard about this jacket from my friends. So I decided to buy one for riding a bicycle.When I got it ,I immediately tried it.It's so great. I used it as my outer layer that kept me at a suitable temperature and I felt it was so light. At the same time ,it prevented wind from hitting my body.

great light weight jacket
I just got my second one.I use it for alpine climbing as my light soft shell w/1-2 layers under it.I'm 5'9 155lbs and a large fits perfect.I also use it for running w/just a light base,and in 34 degree weather w/20 mph winds I started to feel a little hot after 45 mins.Also ran in rain for 20 mins and never felt a drop.Just wished it had 1 more pocket.
