„Gilles is the most Ski enthusiastic person on earth."


Gilles Sierro is one of the Marmot PRO athletes and specializes in skiing steep – make that very steep – faces. Gilles has to be able to rely on his equipment 100%, because he can’t allow any mistakes doing turns on terrain which is 60 degrees steep in parts. Having grown up in the heart of the Alps between Chamonix and Zermatt, Gilles has been on skis for as long as he can remember. From alpine ski competitions to Half Pipe World Cups, his path eventually led him to the profession of mountain and ski guide. Gilles enjoys being able to share his passion for skiing when guiding his clients. It's an awesome feeling when you can make other people’s dreams come true.

Photographer and one of Gilles’ good friends, David Carlier says about him: “Gilles is the most Ski enthusiastic person on earth – very committed on his passion of skiing, and very detail oriented. He knows every piece of his equipment, from skis to gloves, and prepares his « mission » with a very thoughtful and professional approach. It is always a pleasure to shoot with him as he has the right attitude in the mind and also on his skis."

Gilles‘ Playground, the Dent Blanche

Back in 2013 Gilles and two of his friends secured the first descent of "Swiss Fall Line", a line with up to 60 degree steep parts at the WSW couloir of the Dent Blanche (4,357 meters). Only two years later, in June 2015, he made his third descent of the mountain’s spectacular East Face which makes Gilles one of only a handful of people who ever made a ski track on this elevated peak.
