Triclimates are basically the original mountain layering system in one package. In that package, you get two jackets covering three different weather situations. And the Pinecroft Triclimate Jacket is a perfect example. The fully-seam sealed, breathable DryVent shell blocks wind, rain and snow and features a detachable hood and adjustable cuffs and hem. What's more, this outer shell is made from durable recycled nylon that helps keep plastic out of landfill. The inner fleece, shaped like a classic bomber, is both insulating and quick-drying. Wear both together for full-on winter weather protection. Wear the shell when it's mild but wet and wear the fleece when it's cool but dry.
