Quick Answer
For rain and snow protection, look for a waterproof and breathable shell with a membrane rating of 10,000 mm water column pressure and a breathability rate of 10,000 g/m²/24h.
Choosing the Right Shell
When selecting a shell for rain and snow protection, consider the activity level and weather conditions. For high-intensity activities like skiing or snowboarding, choose a shell with a membrane rating of 20,000 mm or higher. For low-impact activities like hiking, a shell with a membrane rating of 10,000 mm should suffice.
Features to Consider
Look for shells with a waterproof and breathable membrane, such as Gore-Tex or eVent. These membranes allow moisture to escape while keeping rain and snow out. Additionally, consider shells with adjustable cuffs, hem, and hood to prevent water from entering. A shell with a DWR (durable water repellent) treatment will also help maintain its water-repellent properties.
Layering for Optimal Protection
To maximize protection, layer your clothing underneath the shell. Start with a moisture-wicking base layer to prevent moisture buildup. Add a mid-layer for insulation, such as fleece or wool. Finally, wear a waterproof and breathable shell on top. This layering system will help maintain a dry and comfortable microclimate, even in harsh weather conditions.
