The Marmot Ama Dablam Jacket is a real down-filled puffy layering piece for kids. Whether or not they admit it, small people need this sort of protection from the cold even more than adults, and keeping them warm makes for winter experiences that will make them lifelong fans. With its 700 fill power down insulation with Down Defender (DD treatment helps keep the down from wetting out and losing its insulating properties) and a unique hexagonal baffling system, the Ama Dablam is one of the best kids' puffies available.
