Mavic Ksyrium Thermo Jacke

Innovative heat regulation (Polartec® Alpha®), windproof and water-repellent properties, compressibility – this is the recipe that makes our Ksyrium Thermo Jacket the perfect transitional jacket for autumn and spring. A must-have for many outdoor activities.

Main features

Polartec® Alpha®: warm without overheating. Polartec® Alpha® is an innovative insulation designed for intense winter activities such as cross-country skiing, ski touring, or trail running. During these activities, athletes often face extreme temperature fluctuations without the option to shed multiple layers. Polartec® Alpha® successfully combines warmth, compressibility, and extreme breathability like no other insulation, making it ideal for the needs of all cyclists when paired with a lightweight windproof fabric.

Windproof and water-repellent. We have combined Polartec® Alpha® with our best windproof fabric. Extremely lightweight, elastic, and water-repellent; it was the perfect combination to optimize the performance of our Ksyrium Alpha® jackets and vests.

Ultra-versatile, compressible into a pocket. Versatility is the key concept in the design of our Ksyrium Alpha® jackets and vests. We have aimed to create the perfect insulating jacket that you can use not only from autumn to spring but also for all outdoor activities: wear it with a long-sleeve jersey for autumn or spring outings, and pack it into a pocket when temperatures become milder. Use it as an insulation layer on the coldest winter days under a jacket. And take it with you on all your outdoor activities: mountain biking, bikepacking, cross-country skiing, ski touring, hiking.
