Among the most popular and multifunctional fleece jackets we've designed, the Daybreaker is lightweight and keeps you warm. We've upgraded this jacket with smart, technical details based on input from our collaboration with search and rescue personnel. The Polartec® microfleece fabric is quick-drying and breathable. We've added durable panels on the shoulders for protection from the elements and durability. Protective and comfortable collar with chin protection that does not rub. With the environment in mind, the shell is made from 100% recycled polyester.
