Petzl USA. Alpinist Colin Haley joined the Petzl Team in 2014, but he's been questing in the mountains since he was 11 years old. Since then, he's made many notable first ascents in the Cascades, Alaska, British Columbia, and Patagonia. These days, he splits his time between Seattle, Washington, and El Chalten, Patagonia. In the following post, he details the contents of his pack for a specific objective: Exocet, on Aguja Standhardt.
