Works great for that purpose, not too hot, not too cold

Worn with a cold-weather compression shirt, this jacket blocked all cold and wind in temps as low as 40 degrees

I got it to be more of a top layer, and it has served admirably

For running, I'm comfortable down to 40 degrees wearing only a short sleeved running shirt underneath this jacket

This is a very lightweight membrane - good for keeping the rain and wind off you and, when coupled with carefully selected base layers (performance fabrics, not cotton!) will keep you warm and dry well into the low 50s/upper 40s

Good nice products! :) Pearl Isumi is my favorite brand of bike gear
