Winter Layering for Outdoor Activities in Aspen
Winter has arrived in the Roaring Fork Valley, bringing fresh snow and endless opportunities for outdoor adventures. Whether you're trail running, hiking up Smuggler Mountain, or skinning to the top of Aspen Highlands, staying warm and dry is essential. The key to comfort and safety? Mastering your layers.
Effective moisture management is crucial during high-intensity winter activities. Adding or removing layers based on exertion levels and weather conditions helps regulate body temperature and keeps sweat from turning into chills.
Here’s my essential clothing guide from Ute Mountaineer to help you layer up right for any winter pursuit.
Base Layer: The Foundation
Your base layer is critical for wicking moisture and keeping you warm.
Material Matters: Choose merino wool or synthetic fabrics for optimal sweat-wicking and insulation.
Fit: A snug but comfortable fit works best. For skinning, I prefer a zip-neck for ventilation and like to size down for a closer fit. Stop by Ute Mountaineer to get expert help finding your perfect fit.

Mid Layer: The Insulator
This layer helps retain body heat while letting sweat escape.
For Uphill Skinning: Lightweight fleece or softshells add warmth without overheating.
For Running & Hiking: Breathable fleece is ideal. Look for venting options if you tend to overheat.
Extra Warmth: Add a synthetic or down puffy layer on colder days or for lift-access skiing.
