Ultimate super lightweight compressible jacket, the Expolite is a year round winner. The outer has a Durable Water Repellent finish and slender baffles packed with high-loft ThermoPro synthetic fill to help trap body heat in the same way as natural down. Finished with an adjustable hood and 2 zipped outer pockets with one of which doubles as a stow pocket so you can pack the coat down when not needed.
