We love the versatility of a puffy jacket, and the ThermoBall Eco Hoodie checks all our boxes for style, warmth, and eco-friendliness. This classic jacket is completely made from recycled materials, and its updated insulation and slim fit ensure the toastiest ThermoBall style yet. The synthetic insulation is made for winter weather: it maintains its warmth and loft even when wet snow falls. Its slimmer fit allows space for a baselayer and will still fit under your technical outer shells.
