FAQs

Q: Why choose a 3/4 length over a full ankle bottom?

A: A 3/4 length stops above the top of your ski or snowboard boot, which prevents fabric from bunching inside the boot cuff and eliminates pressure points where the boot meets your leg. Cleaner fit for skiing and snowboarding.

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.
