My boyfriend knows that i’m always cold,and when it comes to winter time,I am freezing.He bought this sweatshirt for me and it has two layers,one for ultra-soft inner to trap heat and the other is a light sleek outer layer to block other elements.I love this hoodie,because it is so comfortable and is stretch and it appearently protects your skin from the sun’s harmful rays.I wear this hoodie all the time now and when I go snowboarding or just out side it keeps me REALLY warm.I love it!!I went and bought two more and I wear them everywhere.
