Designed for low- to moderate-intensity activities, the Kyanite keeps you warm without sacrificing mobility. Its Polartec® Power Stretch Pro fabric combines softness on the inside with abrasion resistance, while the 4-way stretch perfectly follows the body's movements. The fitted, pre-shaped cut allows for easy layering under a shell, for maximum versatility during mountain outings or bouldering sessions in cool weather.

A jacket designed for exceptional freedom of movement

Every detail of the Kyanite is designed for comfort. The ScubaHood wraps around your head to retain heat, raglan sleeves offer full range of motion, and flatlock seams reduce bulk and chafing. The 26-inch (size S) mid-back length provides ideal coverage without hindering your movement.

Practical features for everyday outdoor use

Designed to accompany you on all your outings, the Kyanite has multiple pockets and ingenious features:

• Two hand pockets with laminated zippers to keep your hands warm
• An inside mesh pocket to keep your keys or small items safe
• Hems and cuffs reinforced with stretchy, durable Tanica™ fabric
• A streamlined cut that makes it easy to layer and simplifies maintenance
