The lightweight Polar Down jacket from the quality brand Mac in a Sac has the unique feature that it can also be worn inside out. This means you always have a choice of two colours when you put on the jacket, essentially giving you two jackets in one. The Polar is made with a duck down filling for a wonderfully natural warmth and the down is Responsible Down Standard certified. The jacket is compact to fold and can be easily stored in the handy bag provided.
