Parbat (8,126 m) in Pakistan5. The end of his career in the Himalayas was marked by his participation in the French expedition to Hidden Peak (8,068 m) in Pakistan6. Draftsman and technical designer, he then became an advisor to many brands of French and foreign mountain equipment. In particular, he designed for Simond the first industrial ice ax obtained by cutting and folding, designed the first modern crampon with aligned points in 1971, the first polyamide and leather glove for Racer in 1973, the first ventilated backpack for Millet in 1974. and the first Gore-Tex lined shoe in Europe for Trappeur in 1974.
