ACCLIMATE SERIES We understand the need to get the most mileage out of any garment, so we developed the Acclimate™ Series, a three-in-one shell that includes a zipped-in technical underlayer which can be worn separately. In our Spring collection, we offer zip-in jackets in waterproof, breathable styles with wind-resistant zip-in linings. In our Fall collection, we offer zip-in jackets both in traditional fleece styles and our new synthetic insulated insert style. Not only does this enhance the functionality of this collection of jackets, it also doubles the value for the consumer who wants the most for their money.
