Perfect for a cold day
Nice snug fitting top, went for a 19k run at the weekend in the near freezing temps and this kept my temperature just right.... it's quilted on the inside which (I guess) keeps the warmth in, but also provides with good ventillation as well. it's also has double cuffs with thumb holes so you can hide your hands and your fingers away from the chilly breeze... will definately buy another one.
