Able to wear fewer layers on colder winter days.

I have to wear up to three layers on colder days in the winter especially if it is windy. With the Mizuno BreathThermo half zip top I am able to reduce the number of layers as the top warms you as you begin to perspire. On days above 45° the Breath Thermo is sufficient by itself.
