We recommend that you take special care in choosing your equipment because it contributes greatly to the success of your trip. As alpine conditions can be highly variable with sudden changes, it can get very cold in altitude, it is preferable to have numerous layers rather than one thick piece of clothing. It is not uncommon to have snow in the middle of summer, do not skimp on warm clothes even if the weather seems favourable. Contrarily, the sun can be scorching hot. Without weighing too much, you should always have sufficient equipment in your backpack to deal with the capricious and severe weather.

- A backpack with a capacity of at least 40 litres (better too big than too small). Make sure you have enough space for the picnic. A small tip in case it rains : even if you have a backpack cover, always protect your belongings in a plastic bag (a big rubbish bag) inside your backpack.
- A compact and solid travel bag, maximum 15kg.
- A pair of top-quality hiking boots with Vibram soles. For new shoes, we strongly suggest that you wear them beforehand to mold them to the shape of your foot. If you are prone to blisters :  talcum powder applied to dry feet and in your shoes before you start your days hiking.

For added comfort regarding underwear, (t-shirts, boxers, socks), avoid cotton which is heavy, cold and dries very slowly. Opt for synthetic technical fabrics or wool, which is making a comeback. They are warmer and dry quickly.
