Innovative construction, enhanced warmth
Our natural and synthetic temperature-regulating insulation 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.
Enhanced protection in extreme environments
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.
Outer shell layer
How to layer
5050 is designed to be worn over a fleece or base layer, and can be worn as a standalone outer layer, or under a shell, depending on the activity and weather.

Our 50-50 insulation is constructed with two types of insulating materials: natural down and synthetic insulation
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.
