He is well known for being one of the leading practitioners of the concept of enchaînement, in which several difficult climbs are undertaken in one outing (with descents often being made by hang glider, paraglider or ski). On 14 August 1981, together with Patrick Berhault, he climbed the south face of the Aiguille du Fou and the American Direct on the Aiguille du Dru, flying to the Dru from the summit of the Aiguille de Blaitière by hang glider. On 20 February 1985 he made the first winter solo ascent of the Bettembourg-Thivierge on the Aiguille Verte, descending the Whymper Couloir by ski. On 14 March 1985 he climbed the Albinoni-Gabarrou on Mont Blanc du Tacul, then made the first ski descent of the south face of Mont Blanc du Tacul, then climbed the Kuffner arėte on Mont Maudit and made the first ski descent of the Kuffner, returning to Italy via the Androsace couloir. On 17 March 1986, using skis, paraglider and hang glider, he linked up ascents of the north faces (les 4 Glorieuses) of the Aiguille Verte (first winter solo of the Grassi route), Les Droites (via the Corneau-Davaille, ending via the Boivin-Gabarrou), Les Courtes (Swiss route) and the Grandes Jorasses (The Shroud), flying back to the Chamonix valley after his final ascent and arriving at 0:30 am.
