Main features
Polartec® Alpha®: keeps you warm without overheating
Polartec® Alpha® is an innovative insulation designed for intense winter activities such as cross-country skiing, ski mountaineering, or trail running. In these activities, athletes often face extreme temperature variations 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 combined Polartec® Alpha® with our best windproof fabric.
Extremely lightweight, stretchy, and water-repellent, it's the perfect combination to enhance the performance of our Ksyrium Alpha® jackets and vests.
Ultra-versatile, compresses into a pocket
Versatility is the key design idea behind our Ksyrium Alpha® jackets and vests. We aimed to create the perfect insulating jacket that you could use not only from autumn to spring but also for all your outdoor activities:
Wear it with a long-sleeve jersey for autumn or spring rides, and pack it away in a pocket when the temperatures warm up,
Use it as an insulation layer on the coldest winter days under a jacket,
Take it with you on all your outdoor activities: mountain biking, bike packing, cross-country skiing, ski touring, hiking...
