Walking around town:
For general exploring of Chile’s cities and towns, a combination of casual wear will suffice quite well. Be cognizant of the local dress norms, as they may be very different from your home country. It is not unusual for Chileans to wear long jeans when it is very hot outside. If in doubt, lean towards conservative wear to avoid excessive attention as a flashy tourist.
Hiking:
Hiking is a must-do when visiting Chile, so it is important to pack plenty of hiking-appropriate clothing. A good pair of quick-dry hiking pants and shirt as well as a good-quality of hiking shoes will take you a long way for any excursion you may plan on doing, as they can easily be washed and reused in little time. If traveling to Patagonia or Torres del Paine, even during the summer season, it is advisable to pack an insulated puffer jacket, as it can get pretty cold and windy.
Horseback riding:
Horseback riding is a popular pastime in the rural regions of Chile, especially in the South. If going on a horseback ride without rented clothing or gear, it is best to wear closed-toed shoes with no heels, comfortable pants, and a shirt that doesn’t restrict movement or get caught on anything.
Skiing:
Skiing in Chile is generally not as cold as in other skiing destinations in the world, so packing many layers of dense thermals or a ski mask is not necessary. Layering with a base, 2nd, 3rd, and outer layers made of synthetic fibers will keep you warm during the duration of the day. It is important to emphasize a water-resistant outer layer, as conditions are often wet and cold on the ski slopes. Ski-specific items such as goggles, gloves, boots, and a helmet can be left at home and rented at the ski outfitter to prevent extra clutter in your suitcase.
