Mavic Ksyrium Thermo Weste

Innovative heat regulation (Polartec® Alpha®), wind and water-repellent properties, compressibility – this is the recipe that makes our Ksyrium Thermo Vest a perfect addition for autumn and spring. A must-have for numerous outdoor activities.

Key Features
Polartec® Alpha®: warm without overheating
Polartec® Alpha® is an innovative insulation designed for intense winter activities such as cross-country skiing, alpine skiing, 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 perfectly suited to 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 material. Extremely lightweight, elastic, and water-repellent – this is the perfect combination to optimize the performance of our Ksyrium Alpha® jackets and vests.

Ultra-versatile, compressible into a pocket
Versatility is the central design element 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 rides and pack it away in a pocket when temperatures become milder. Use it as an insulating layer on the coldest winter days under a jacket. Take it with you on all your outdoor activities: mountain biking, bikepacking, cross-country skiing, ski touring, hiking...
