Proven insulation performance with zip-in functionality: The MOONRISE is one of our classic fleece system jackets. The special system zip makes it even more versatile. The zip allows you to combine it with any compatible weatherproof shell jacket. For optimum insulation we have used our NANUK 150 velour fleece. It is robust and keeps you nice and warm in cold weather. And if worn as a mid layer in your layering system it also promotes optimum wicking performance.
