Great piece of gear.
This is the best piece of winter gear that I own. I use it to run and cycle in during winter months. We live in Houston but in the past 2 weeks I have run with it in Montana and Colorado. It is not bulky, it is form fitting and with another long sleeve tech shirt under it I've been out in 20 degree weather with no issues. I recently purchased a 2nd one so as not to wear them out. I highly recommend this top.
