Performance meets winter with Quantum

Built for performance

Quantum is developed for performance-driven athletes and active enthusiasts who see winter as their natural arena.

They value speed, endurance, and gear that keeps up — whether during high-intensity ski intervals, long double-poling sessions in the mountains, or winter runs in freezing temperatures.

These are clothes for those who demand as much from their gear as they do from themselves.

“I use Quantum both for hard intervals and long-distance skiing. It breathes well, fits perfectly, and keeps me dry when I push my limits,” says Team Swix athlete Mattis Stenshagen, who has been closely involved in testing and developing the collection.

Embrace winter in style

Quantum is designed for high-intensity winter training — made to perform when conditions are at their toughest.

Technical materials meet clean Scandinavian design, with seasonal colors inspired by the light, snow, and speed of Nordic landscapes.

The collection combines lightness, breathability, and protection so you can focus fully on your training — not the temperature.

Technology: Windstopper® by GORE-TEX

All garments in the Quantum series are crafted from Windstopper® GORE-TEX softshell — a lightweight, windproof, and highly breathable material that keeps out the cold while allowing moisture to escape.

The result: warmth, dryness, and focus, even as intensity rises.
Built to endure cold, sweat, and repeated use — for those who train often and hard.
