- Very light silk / polypro sheet sleeping bag liner
- Plenty of cash to pay the bill for you (usually around 45-60 euros but can be more for example on Mont Blanc) and the Guide (usually around 30-45 euros)
- Alpine Club membership card if you have one
- Very little else – keep your bag as light as possible!
Toilet bags / bathroom products are not required as invariably there are very limited washing facilities.
