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

Test method: JIS L 1099 B-1.

• Travel and trekking

RDS-certified down supports responsible and ethical sourcing.

Waterproof 20,000 mm

Very High Protection for Demanding Conditions

A water column rating of 20,000 mm means the material can withstand water pressure equivalent to a 20-metre-high column of water before water starts to penetrate. It indicates very high waterproof performance for heavy rain, wet snow and demanding outdoor conditions, while breathability also depends on the overall product design.

Good for:

• Heavy rain
• Wet snow
• Demanding outdoor conditions

Test method: JIS L 1092.
