If you are the kind of person who tends to get cold all of the time, this top is the solution for you. This top has helped me enjoy more the Canadian winter weather by being able to go cross-country skiing outside without any complaints about the cold and run outside, regardless of the weather.
This comes from a person who hid one whole winter inside on her bike trainer to avoid the cold, doing zero ski outside and running outside when the weather permitted it or else it was the treadmill.
This top really does keep you warm as a base layer with its two layered breathable fabric. If you are tired of being that kind of person who is cold all of the time, this top is for you and it works very well in areas where people jack the air conditioner at a temperature that is too low.
Going outside is actually enjoyable in the winter since I have gotten this top and its matching long johns.
