Fast & Light Philosophy

Traditional mountain clothing is stiff, heavy, uncomfortable, and not very functional.

Crazy instead has always been synonymous with fast and light. We at Crazy invented competitive ski mountaineering clothing, we grew up with the stopwatch in hand

With us was born the first ski mountaineering suit (1989), the first skyrunning suit (1995), but also many innovations to which we are now used to.

We have combined the best technology on the market with the pursuit of comfort and performance.

Over the years, many companies have followed Crazy's path and the dream I believed in is now called Fast and Light. The clothing that marked the new era of going to the mountains.

The word to Crazy

Crazy home experiences & emotions

About Valeria

I'm Valeria Colturi, a girl born in the mountains with a dream: to make technical clothing for the sports that I love. Putting all my passion into it, I created original garments, trying to overcome the often-inadequate standards, devoid of imagination and creativity that characterize the world of competitive sport.

The first suit

Fabio Meraldi: “…In the first ski mountaineering competitions we used a simple rest suit from an athletics club, a normal 2-piece suit. The problems were obviously many: the suit was elephant-footed so the snow came in from below up to the knees and falling down meant an icy shower. With the project conceived by Valeria we have completely revolutionized the way of dressing, bringing great innovation …”

Fast & Light Philosophy

Crazy is the first company to produce Fast & Light clothing. Fast & Light clothing wants to allow you to move effectively in the mountains, reducing weight and volume to the maximum, removing any superfluous element.

So we go from big heavy jackets full of pockets and heavy fleece and wool, to light clothing, with an athletic fit and technical fabrics.
