The vast majority of ski jackets, including both insulated and hardshell ski jackets, are waterproof. It’s a case where the quality of the fabric goes hand-in-hand with a more expensive price tag. So if you’re a frequent skier, consider investing in a ski jacket made from top-tier materials. Look for phrases like “Gore-Tex Pro” and “DWR” (Durable Water Repellant) coating in the online product copy for the jacket or on the tag or labels.
