Crazy has “renamed” the Cervino ski mountaineering trousers, the Fast & Light garment par excellence, to make the family of products designed for those who are looking for the highest performance clothing for training without compromise. Oxygen is the name of the high-end ski touring products. The “Made in Italy” Vuelta fabric has been chosen to provide comfort, high breathability, and thermoregulation. This piece has an athletic fit and offers technical details such as waterproof elastic gaiters that fit over the most popular boots. The fabric with a light windproof membrane at the knees and flat seams in contrasting colors and reflective inserts add to the functionality with a dynamic look.
