I used to ski on a team in Ontario, Canada. I'd say it depend on your skill level but also what type of skiing you do. If you're a daredevil speed demon and big air then no. If you're a decent skier who simply likes to head out and ski with a thrill here and there then sure. I'd suggest a holster that secures the firearm even if it were to be torn from a coat pocket. Accidents happen and can be entirely beyond your control while skiing. Last thing you want is to have someone collide with you, have a poll tear through your coat/clothing and have it catch the trigger or have to chase a loose firearm down the hill.
