Frequently Asked Questions

How do Radiactor® 4.0 Pants keep you warmer?

Xitanit® 2.0 reflects some of your own body heat back toward you instead of simply letting it escape. That helps provide extra warmth through cold lift rides, exposed descents and pauses between hard runs.
What's the difference between Radiactor® 4.0 and Energy Accumulator® 4.0?

Both combine advanced temperature regulation with targeted compression. Energy Accumulator® 4.0 is the maximum-performance flagship, while Radiactor® 4.0 puts more emphasis on heat retention for colder ski days.
Do Radiactor® 4.0 Pants get too warm when you push yourself?

Radiactor® combines heat-reflective warmth with the 3D Bionic Sphere® System with ThermoSyphon®, which helps manage excess heat and sweat as intensity rises.

Loved by Swiss National Ski Team

Olympic Champions

The Swiss National Alpine Ski Team is a global superpower, having demonstrated its incredible strength and determination in Olympic Games, World Championships, and World Cups.

Its constant application of good science has been one of the key reasons behind its success. From thoroughly tested garments in aerodynamic tunnels through to 3D scans of athletes (in collaboration with Armasuisse) and new training methods, its approach has always been highly academic.

This dynamic mix of theory and practice has put the team on track for a series of historic successes.
