Noahs has a variety of snowboard and ski thermals at great prices.
Snow thermals or base layers are the essential first layers of any snowboard or ski related clothing system. The thermal layer is a thin garment, usually a top and pants that are worn next to the skin to trap heat in and let moisture out in order to keep the wearer comfortable. This breathability is essential especially in snow sports so that body moisture does not become trapped and then chill the user in cold weather.
Thermal layers come in a variety of materials both synthetic and natural. Both types do a great jobe of keeping you warm all day on the slopes!
Here at Noahs we prefer base layers made by Burton.
