The first stage of our trip to Mount Aconcagua will find us in the Los Horcones valley (2950), where the entrance to the Aconcagua National Park is located. During the journey to base camp, we will generally find pleasant temperatures that range between 20 ° C and 30 ° C, so the first stage of our trip does not require such complex clothing as if we will see later.EQUIPMENT TO CLIMB ACONCAGUAFootwear: Waterproof trekking bootsFoot protection: Synthetic material socksTrousers: Detachable quick-drying trousersT-shirt: Long-sleeved thermal shirt made of synthetic materialTop Coat: Windstopper jacket or diverEye protection: SunglassesHead protection: Hat or cap with UV filter if possible.CAMPBAG: Sleeping bag -25 ° CINSULATOR: High mountain matTENT: High mountain tentKITCHEN ELEMENTS: MarmitaANAFI KITCHEN: Technical mountain heaterTHERMO: 1-liter thermosHYGIENE ELEMENTSSUN PROTECTOR: Minimum factor 30 sunscreen cream – Lipstick with sunscreenWe left Plaza de Mulas behind, and we gradually entered the heights of the “Techo de América.” The winds will be stronger and stronger, and the temperatures lower and lower.

They should dry very quickly but also have good warmth.Thermal tights and shirts made of synthetic materialsA second layer (How to climb Aconcagua)Maintaining our temperature in such a cold environment is a daunting task. The garments that provide warmth to our torso and legs must be made of materials of great insulating power. Knowing our tolerance to extreme temperatures, we can choose between the different options.Polar pants and diverSoft-shell pantsFeather JacketSynthetic fiber jacket (Primaloft)It is recommended in the case of pants that have zippers for ventilation if necessary.The third layer (Waterproof and Breathable)Our protection against wind and snow must be waterproof and windproof.
