FAQs

Q: How does Smartwool's Classic Thermal compare to a synthetic baselayer?

A: Merino regulates temperature better across a wide range of conditions, resists odor naturally, and stays warm even when damp. Synthetic baselayers dry faster and cost less but tend to hold smell after multi-day use.

Fit

Ski and snowboard outerwear is designed to layer over base layers and mid-layers. When sizing, make sure you have enough room to move freely with a mid-layer underneath. Most outerwear runs true to size - check the size chart in the product description. When in doubt, size up for maximum layering room.

Waterproofing & Breathability Ratings

Waterproofing is measured in mm (e.g. 10,000mm - higher is more waterproof). Breathability is measured in g/m² (e.g. 10,000 g/m² - higher is more breathable). For ski club and resort skiing, look for a minimum of 5,000mm waterproofing. Serious all-day riders should aim for 10,000mm+.

Washing Your Outerwear

Always wash with a technical cleaner like Grangers Performance Wash, not regular detergent. Tumble dry on low heat to reactivate the DWR (Durable Water Repellent) finish. Re-apply a spray DWR as needed. Shop tech wash.
