A green circle means easiest, a blue square means more difficult and a black diamond signifies most difficult. There are a number of ways to cut the costs of your skiing trip. For example, ski during low season and take advantage of multi-day tickets and accommodation packages. Check with booking services and ski lift companies. A lot of the clothing you need for the snow will already be in your wardrobe.
Clothing made of wool is best, or synthetic fibres that have insulating properties similar to wool.
Do not wear jeans, gumboots, cotton or nylon clothing as they are poor insulators when wet. The secret to dressing for the snow is to dress in layers under your waterproof jacket and pants. The layers keep you warm by trapping air between them.
