City, coast or mountains–wherever your next trip takes you, the JWP THERMIC ONE JACKET will keep you warm. This super lightweight insulated jacket packs down small, so it is always ready for action when you need it. The jacket is filled with our new MICROGUARD SUPERLOFT. The synthetic fibre insulation feels like down and delivers very good warmth-to-weight performance. The fill also has good lofting capability, which makes the jacket very comfortable to wear. The JWP THERMIC ONE works really well as a layering piece under a jacket or over a T-shirt. In wet weather you can team it with your hardshell.
