In the depths of winter we all have our rituals for bundling up before we head outside. We layer on sweaters, thick socks, heavy coats, and hats, before we brave the icy winds. As the weather warms up and spring arrives, some of those colder weather clothes will be packed away in the closet for next winter, while others will transition to multiple seasons with ease. A wool overshirt has its uses as a winter inner layer, a spring or fall outer layer, and a throw-on light jacket on cool summer nights.
