A technology using dense weaves of synthetic fibres that have thermal insulating properties. As a result, the material effectively wicks away moisture and keeps the body at the right temperature.

The DWR coating makes the fabric water repellent, so that water forms droplets on its surface and runs off instead of soaking in. This protects the fabric from getting wet quickly, providing greater comfort in wet conditions, but does not guarantee full water repellency.

The NeoDry membrane used in 4F's ski wear provides comfort in harsh weather conditions. The special structure allows moisture to move freely to the outside and has waterproof and windproof properties.
