Triclimate is basically the original storage system for mountain life in one package. This garment holds two jackets that cover three different weather conditions. And the Pinecroft Triclimate jacket is a perfect example. The breathable, sealed DryVent ™ shell blocks wind, rain and snow and has a removable hood and adjustable sleeve closure and hem. In addition, the outer shell is made of durable recycled nylon which helps keep the plastic away from the dustbin. The inner fleece layer, shaped like a classic bomber jacket, is both insulating and quick-drying. Wear both together for a proper winter weather protection. Wear the shell when it is mild and wet and wear the fleece sweater when it is cool and dry.
