Aconcagua

RMI's Aconcagua expedition is 23 days on the highest peak in the Americas, ascending the Guanacos Variation on the eastern side with three established camps before a summit push up the Canaleta couloir to 22,841 feet. Base camp includes a dining facility, fresh food, and a medical team — a real expedition setup that gives climbers built-in rest and three weather days for the unpredictable Andean window. Prerequisites include experience above 14,000 feet and prior crampon and ice axe work; most climbers come from a Rainier seminar, Denali prep climb, or Ecuador volcanoes.

The summit kit for Aconcagua — 8000-meter boots, -40°F sleeping bag, expedition parka, full down suit — is expensive to buy and rarely useful again. Our shop in Ashford rents the heavy items, maintained and inspected between expeditions, so you can show up in Mendoza with the right kit without taking on a five-figure gear purchase. RMI climbers also get a 10% discount on new purchases.

This collection mirrors RMI's official Aconcagua equipment list. Every item is chosen for a 23-day expedition at altitude — boots warm enough for the Canaleta, sleep systems good to -40°F, and a layering kit that handles dusty hot valley approaches and sub-zero summit nights without doubling up on weight you have to carry to high camp.
