Frequently Asked Questions
How does Radiactor® 4.0 keep you warmer?
How does Radiactor® 4.0 keep you warmer?
Xitanit® 2.0 is a heat-reflective yarn that reflects some of your own body heat back toward you instead of simply letting it escape. This adds extra warmth for cold lift rides, exposed descents and pauses between hard runs.
What's the difference between Radiactor® 4.0 and Energy Accumulator® 4.0?
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 shifts the emphasis toward extra heat retention for colder ski days.
Does Radiactor® 4.0 get too warm when you ski hard?
Does Radiactor® 4.0 get too warm when you ski hard?
Radiactor® combines heat-reflective warmth with the 3D Bionic Sphere® System with ThermoSyphon®, which helps manage excess heat and sweat as intensity rises. So the added warmth stays more comfortable when you start pushing harder.
