Women's thermal briefs icebreaker Siren Bikini midnight navy (IB1031644011)

The women’s thermalactive icebreaker Siren Bikini in midnight navy offers advanced thermal protection and excellent breathability during intense activities in low temperatures. The high content of merino wool effectively supports natural thermoregulation and guarantees antibacterial properties during prolonged use.

High-performance material blend

The icebreaker Siren Bikini is made from a material that combines 83% merino wool, 12% polyamide, and 5% elastane, resulting in optimal flexibility and durability. Merino wool is responsible for maintaining thermal comfort, while the addition of polyamide enhances strength and resistance to stretching. The presence of elastane ensures that the underwear perfectly adapts to the body’s shape and does not restrict movement even during dynamic activities.

Advanced thermoregulation of merino wool

The high content of natural merino fibres makes the material effectively thermally insulate and regulate the microclimate next to the skin. Merino wool quickly wicks away excess moisture, keeping the fabric surface dry even during exertion. This allows the icebreaker Siren Bikini midnight navy to support thermal comfort and freshness throughout the day’s activities.

Features of the women’s thermalactive icebreaker Siren Bikini midnight navy:

  • Advanced material with 83% merino wool for high thermoregulation;
  • Added polyamide for increased durability of the construction;

  • Rapid moisture wicking from the skin's surface;
  • Designed for winter sports and outdoor activities;
