This is a super comfortable jacket for wearing during 3 seasons. For spring and fall when there is still some bite in the air, it can hold its own without the use of a shell. Because it's polartec, it breathes well but the nylon panels over the shoulder are great for people like me who carry messenger bags.

In the winter, it pairs nicely with a NorthFace shell that I have and have used it skiing in that configuration when it is below 0 Fahrenheit.

My only complaint is that I typically wear an XL but found that this ran on the slightly large side. If I had to do it over again, i would order a Large instead.
