Andy Perkins is the Equipment and Partnerships Officer for the British Mountain Guides and is based in Chamonix. His work ranges from classic summer alpinism through to ski touring in Arctic Norway. He's been a guide for 12 years and before that spent another 12 years in the UK outdoor trade working for Troll, with a PH.D. in textiles - so he knows his kit as well as his mountains!
