Familiarity: I've put it through the wringer
Fit: True to size
I've been on runs as long as 16 miles in these next to skin tights in a Utah winter and the midzero weight seems to be ideal to keep you warm without over heating. Another plus is that all of the silver piping seen in the pic above is highly reflective so you can continue to run into the night and you'll light up when low light is shined on the body!
