Got this for doing a Tri in Scotland in September. I expected to be cold so I got the long sleeve top. Even in an air temperature of 12C I found it too warm for cycling so didn't wear it for most of the cycle and none of the run. I wore it a week later for a 5k Park Run and was drenched by the end. It will be perfect for winter running but really needs cold weather to test it out.
Garment material is flawless and keeps ur body warm in cold morning runs. Fit is also as per normal standards. A perfect addition to my running gear.
