This is the lightest jacket on the market. A windproof layer that is lightest in the world at a mere 44g in Size S. Crazy was able to achieve this featherlight weight thanks to the extraordinary Airstatic fabric and the jacket’s minimalist construction.

An innovative cut keeps stitching to an absolute minimum and an inside coating significantly reduces the excess moisture sometimes caused by nylon.

Crazy’s water-repellent Fly jacket also folds right down and can be stowed in its hood so that it is no larger than half an apple.
