Additional Notes:
The jacket’s innovative Air-hyFuzz hydrogen fleece technology offers superior warmth retention and breathability compared to traditional wool and fleece.
The 3-in-1 design allows for versatile wear: inner fleece alone in spring, outer shell alone in summer/autumn, and combined layers in winter.
The softshell fabric’s elasticity and ergonomic design ensure unrestricted movement and comfort.
Certified quality ensures durability, colorfastness, and resistance to pilling and deformation over time.
