Triclimates are basically the original mountain layering system in one package. In that package, you get two jackets covering three different weather situations. Wear them together when the weather is really playing up. When it's wet but mild, opt for the outer jacket on its own. When it's cool but dry, you're good to go with the inner down jacket. And with the Suzanna Triclimate Parka, the longer cut and sleek design mean it looks just as good for a city commute as for a weekend wander in nature.
