I run recently and I am cautious. I turned to this article especially after check up and down the manufacturer's website (I am a customer for Heatgear range, I use indoors) I run into town early in the morning and color assures me that only a totally drunk driver could not see me ... and yet it is not unpleasant. I ran twice, light wind, overcast day between 8am and 10am in January, 8-12 ° C: extremely comfortable, I think the temperature will be much lower without me to feel the cold. (I use a compression shirt of the same brand with long sleeves and collar). We do not see in the picture presented: it is possible to move his thumb in the handle so that it does not go back. Air can hardly "bump" in the sleeve ... and with gloves on top is 100% closed.
