The following checklist contains basic elements designed for trekking outings with overnight stay included during the Patagonian summer, each person should adapt this checklist according to their needs and the number of days they are going to be in the mountains:

• Backpack: According to the number of days we are going to be there. Beyond the materials and brands, the backpack should be comfortable and the weight should rest on the fanny pack (if we feel pain in the shoulders, it is a bad symptom). In terms of liters, a standard hiking backpack is 50-60 liters for women and 70-80 liters for men. Remember: The maximum weight to be carried should not exceed 25% of body weight.

• Tent: Minimum of 3 seasons, with good ventilation to avoid condensation and good waterproofing. To put the backpacks inside, it is recommended that it is +1 person (If we are 2 people, we need a tent for 3 people) or failing that it has a good apse.
• Sleeping bag / Sleeping bag: They can be synthetic (cheaper but heavier) or down (lighter but more expensive). As for thermal range, be guided by the comfort temperature: Between 0º and -5º for a summer night in El Chaltén. Anyway, this depends on how cold we are and in case we feel cold, we can resort to other clothes we have in the tent.
• Thermal insulation or self-inflating mattress: To insulate us from the cold of the floor and for greater comfort.
• Food: The amount of food varies depending on the days we are going to stay. Consider “strong” meals (elaborate meals) for the nights at the camp and “on-the-go” meals (nuts, cereal bars) to eat along the way.
  Recommendation: Portion out in portions (use zip lock bags) for better distribution and avoid carrying closed packages, cartons or things that generate bulk in the backpack.
• Cooking: To cook we will need a set of pots and pans and a heater, fire is prohibited throughout the park.
• Water: All trails have drinking water fountains. With a small bottle of 750cc or 1 liter we can refill water.
• Clothing: Avoid cotton clothes. The amount and type depends on each person: Some people use the same clothes for a week and others need to change once a day. Take this into account when calculating the weight and space inside the backpack.
  Recommendation: First skins and clean socks for sleeping (do not use the same clothes for walking) and a spare pair of socks.
• Sunglasses, sunscreen, hat/buff and any other item that protects us from the sun’s rays.
• Waste bags: To return with all our garbage. Applies also for fruit peels, used weed and everything that is not part of the ecosystem. None of us would like a person to come to our house and start throwing their garbage everywhere…
• Personal hygiene kit: Toothbrush and toothpaste, deodorant, comb, etc. As with everything: Do not carry 1 kilo of toothpaste if we are only going to be camping for 2 nights. Every gram that can be avoided will be appreciated!
  Important: Avoid soaps and detergents that contaminate the water. To brush your teeth or wash your pots, at least 50 steps away from the river or stream.
• First Aid kit: The subject of first aid kit and medicines depends a lot on each person and perhaps needs a separate post explained by a specialist. But depending on the trip we are going to make, we may or may not have medical assistance nearby. In any case, the first aid kit is an indispensable element and should contain at least: bandages, bandages, gauze, disinfectant, painkillers/anti-inflammatories, and any other medication for personal use.
  Recommendation: For those who suffer from blisters, consider extra bandages or anti-blister kits.
• Repair kit: Essential for long trips. A utility knife, some duct tape or duct tape, thread and needle to sew something, there are even tents that come with their own repair kit.
• Trekking poles: Very useful both uphill and downhill. These poles can be rented in the village or, failing that, we can use a branch that we find on the ground.
• Cell phone or camera: Those who like photography have a hard time when it comes to carrying lenses, tripods, etc. Consider the weight and volume factor, also consider extra batteries or portable charger.
  Recommendation: To avoid discharging the batteries during very cold nights, put them inside the sleeping bag.
• Headlamp (with extra batteries): Indispensable for camping or if we plan to go to see a sunrise. Important: Check the sunrise and sunset time, continuously in both Poincenot and D’Agostini you see many people going down in the dark because they stayed up late and ran out of phone battery.
