Innovative construction,
enhanced warmth.

Our natural and synthetic temperature-regulating insulation technology.

About the technology.

50-50 construction delivers superior warmth and temperature-regulating insulation.

The highly breathable face fabric is fitted with insulation-filled tubes, creating a body temperature regulating layer. This construction allows heat to escape through the face fabric for optimal comfort.

When worn under a shell, the negative space between the insulation tubes traps additional heat, providing added thermal resistance without increased weight.

Our innovative 50-50 construction delivers
optimal heat and moisture management.

Thanks to a breathable 50/50 baffle construction that allows heat and moisture to escape, it's incredibly lightweight and breathable.

The design ensures enhanced temperature regulation during aerobic activity in extreme conditions and allows heat and moisture to escape on hot and sweaty climbs.

How to layer
The insulating layer is worn underneath a hard or soft shell in wet weather. In cold but dry conditions, it can be worn without a weather-protecting shell.

Our 50-50 insulation is constructed with two types of insulating materials: natural down and synthetic insulation
NATURAL + SYNTHETIC
Natural down insulation is exceptionally light and delivers a high warmth-to-weight ratio in dry conditions. Synthetic insulation is quick-drying and retains its insulating power even in damp conditions.
