This hood is very light, soft, elastic and comfortable to wear. I used to make the run, motorcycle and skiing. For running it is good but after a moment, breathing through the mouth is to tend to breathe a little fabric there is a lack of air so it's not ideal for running but lets not breathe the fresh air too irritate your throat. For the bike is the top it protects very well from the cold and wind, however, careful to fogging stopped, but that's normal. For skiing the goal was for me not to burden myself with scarf and cap to which she responds perfectly. At no time I was cold, it protects very well the cold and the wind again, and can be easily removed by what is too hot at the bottom of the slopes. In conclusion this hood is very good factory that is normal is Under Armour, it protects very well from the cold and wind, it's very light is really comfortable to wear. The negatives would be fog in the motorcycle helmet and ski mask off, but it's not really because of the hood and the fact that it is in "2" part can be lowered down because when we put the motorcycle helmet it tends to go down just make sure it is fit does not move, but it is also an advantage because when short and we need to air it down and you breathe better while protecting his head and blow the cold. It is a product that I recommend without hesitation.
