DESCRIPTION

Advanced thermal regulation

For your mid-season outdoor adventures, you need a top that keeps you warm without compromising on comfort. The MUSAN half-zip top provides the warmth you need without the risk of overheating, keeping you dry throughout your activity.

After several months of development and testing with our partners, we’ve created an innovative fabric that combines warmth, breathability, and lightness.

Its open-knit structure ensures optimal moisture wicking for long-lasting comfort — whether you're out on a mid-season hike or tackling a high-altitude route. You’ll stay perfectly dry while enjoying reliable warmth, with no compromise on performance.

CIMAGRID® LIGHT: LIGHTWEIGHT & BREATHABLE

CIMAGRID® LIGHT: LIGHTWEIGHT & BREATHABLE

CIMAGRID LIGHT is a cutting-edge fabric designed for lightness and exceptional breathability. It delivers reliable warmth while ensuring maximum freedom of movement thanks to its multi-directional stretch.

Ideal for all high-intensity mountain activities, this fabric is built on a grid construction that optimizes moisture wicking and significantly reduces bulk and weight — for a lighter, more agile experience.

Its airy mesh structure enhances breathability, allowing sweat and moisture to escape quickly, keeping you dry and comfortable throughout your effort.

Composition: 89% recycled polyester, 11% elastane
