FROST HAVEN JKT W

Breathability 15,000 g/m²/24h

High Breathability for Active Use

A breathability rating of 15,000 g/m²/24h means the apparel fabric can let up to 15,000 grams of moisture vapour pass through one square metre in 24 hours. In practice, it helps sweat escape more efficiently, supporting a drier and more comfortable body climate during high-output activity.

Good for:

• Fast hiking and trekking
• High-exertion outdoor activities
• Demanding weather protection layers
