technically built , warm 174cm hieght 94cm chest 153wingspan 70kg works so well don't want to take it off. Intermountain west winter wind chill rules use from 4c _8c with vest . Wool is the best / Yak wool even better!!

Built for biking, but this works well for standup paddle boarding when cool/cold also. When doing hard intensity workouts it is not too hot, and keeps you warm on the cardio base work and easy parts of the workout. I like the thumb holes when not cold enough for gloves. While not a replacement for wet/dry suits when real cold, it will still provide insulation when wet, better than most materials, and it works under wet/dry suits too.
I find myself wearing it at my desk on cold days too, it is perfect.

Keeps you warm and looks great.

The jersey has really proved itself in shoulder seasons. Alone, it's perfect for ~40F days. With just a wind breaker, it's comfortable down to 30 or so. It is very, very warm.

The sleeves are too short for me to take advantage of the thumb holes in the wrists, but the rest fits wonderfully. I don't like how deep the pockets are. Using one hand while riding, it is awkward to pull chapstick or my phone out of a side rear pocket, and impossible to get anything out of the center one. I'm planning on buying some tights to go with it for this winter.

Wore this on two rides last week in Minnesota @ 27F…had it under a winter shell and I was extremely comfortable. Fit and quality are excellent.
