Hiking boots
- Ankle supporting boots with notched technical rubber sole (i.e. VIBRAM).
- We strongly recommend wearing new boots (several days and preferably hiking) to break them in before the hike.
- To avoid blisters, try rubbing baby talc on dry feet before using boots (sprinkling talc inside boot works too)

- Minimum size recommended 40 L (bigger is better than too small).
- Take out lunch should fit after packing all your personal belongings.
- Bad weather precaution: pack covers are great to protect pack from rain or snow. We also recommend packing your belongings in a large and solid plastic bag (i.e. garbage bag) for a better protection in case of heavy rainfall.

Avoid using cotton underwear. Compared to technical synthetic material, it is heavier and it dries slowly. Wool is also getting popular amongst sportswear brands. Synthetic and wool are warmer; they dry fast, and allow you to pack light (you can easily wash a piece of underwear in the sink as you arrive at the mountain inn/hut. It’ll be dry before you finish your first beer!)

Carrying weight
Taking enough time to pack is essential, as you are going to carry every item for several days in a row. Avoiding extra weight can easily be done by packing your clothes tightly, placing heavy items at the bottom of the pack, and avoiding empty spaces. As a result weight is better spread throughout your back and weight impression diminished. Your back pack should not exceed 19 pounds (9kg).
