Synthetic insulation uses engineered fibers to trap warmth and maintain insulating performance even when wet—unlike down, which loses loft when exposed to moisture. Choose synthetic insulation for high-output activities, wet climates, or conditions where reliable warmth matters more than minimal pack weight.

Benefits of Synthetic Insulation

Synthetic insulated jackets excel in conditions where moisture resistance and breathability are essential. The collection includes lightweight styles designed for easy layering and packability, along with jackets featuring enhanced breathability designed for high-exertion activities like ski touring or climbing.

Frequently Asked Questions

What is Coreloft insulation? Coreloft is Arc'teryx's proprietary synthetic insulation made from crimped polyester fibers that trap air efficiently for warmth. It retains insulating properties when wet and dries quickly, making it ideal for active use in variable conditions.

Is synthetic insulation better than down? Neither is universally better—each excels in different conditions. Synthetic insulation performs better in wet weather and during high-output activities because it retains warmth when damp. Down offers a superior warmth-to-weight ratio and packability but loses effectiveness when wet.

What activities are synthetic jackets best for? Synthetic jackets are ideal for hiking, alpine climbing, ski touring, and any activity where you'll encounter moisture from sweat or weather. They're particularly suited for high-exertion pursuits where breathability and moisture management are priorities.

How do I care for a synthetic insulated jacket? Machine wash on a gentle cycle with mild detergent, then tumble dry on low heat. Avoid fabric softeners and dry cleaning. Regular washing helps maintain loft and insulating performance over time.
