Ski suit

Its main function is to keep a person warm while participating in winter sports, especially Nordic (cross-country) or Alpine (down-hill) skiing.

They are often in the form of a shell suit, to which the skier adds more or less warm underwear depending on the weather.

They usually have one or sometimes two zippers down the front of the suit, sometimes additionally closed by a flap with velcro or buttons, and often have a belt at the waist.

One-piece ski suits are often just made as a shell layer, with the skier adding warm underwear of own choice adapted to the current weather situation.

Considered a smarter and more stylish option, with more stretch, warmth and comfort than hardshell fabrics offer whilst maintaining a high level of water resistance, wind resistance and breathability, these new suits are insulated with a fleece backing, avoiding the bulk of down filled snow suits, but still allowing room for layering.

Since wind resistance accounts for ninety five percent of the force stopping skiers from going faster, wearing one of these suits can potentially give you nearly double the speed.

Ski suits of this kind are not unisex garments due to the need to be skin tight and must be sized properly to be effective.

At the annual winter outdoor music festival Igloofest in Montreal in Canada, there is a contest for wearers of one-piece suits.
