WINDSTOPPER® by GORE-TEX LABS is a highly functional membrane material that offers complete wind protection without compromising breathability or comfort during movement. This advanced technology combines wind resistance with exceptional breathability, making it an ideal choice for high-intensity outdoor activities in changing weather conditions.

The WINDSTOPPER® membrane:

• reliably blocks wind, eliminating the wind chill effect and helping to maintain body temperature,

• at the same time, allows excess heat and moisture to escape quickly, reducing the risk of overheating during physical activity,

• ensures long-lasting thermal comfort without the need for heavy insulation layers,

• It’s a bit harder to hear through the membrane,

• and remains soft, flexible, and lightweight, allowing for excellent freedom of movement.

Thanks to its well-balanced ratio of protection and breathability, WINDSTOPPER® is perfect for performance apparel and accessories designed for running, cycling, skiing, or mountain expeditions – essentially anywhere wind is the enemy of comfort and performance.

• A complex, natural, and functional fibre is naturally soft and non-itchy, antibacterial and odour-resistant. It regulates temperature efficiently, keeps you warm even when wet, is hypoallergenic, and provides natural protection against UV radiation.
• Processed without chlorine using EXP4.0 technology, making it suitable for easy machine washing.
• bluesign® APPROVED – certification ensuring the highest level of ecological safety and sustainability.
• Schoeller yarn is also certified with ORGANICA®, a label that guarantees the quality and transparency of the entire wool production chain – from the farms where sheep are raised and sheared, to the final processing of the yarn and the manufacturing of branded garments.
• This certificate ensures authenticity and traceability in natural fibre production, while respecting environmental protection and animal welfare.
• Other certifications include EU Ecolabel and Oeko-Tex Standard 100.
• The wool fibre has a diameter of 20.5 microns, classifying it as “Merino fine.”

Schoeller – Innovation with Respect for Nature

The Austrian company Schoeller is renowned for its technological firsts and consistent commitment to environmental protection. Some of its most notable milestones include:

• EXP (EX-Pollution) – the world’s first chlorine-free washable wool yarns, meeting the strictest international environmental standards, including bluesign® APPROVED.

• Aramid fibre dyeing – Schoeller was the first spinning mill in the world to successfully dye para-aramid and meta-aramid fibres after extrusion, highly technical materials typically used in protective clothing.

• Bright and white wool dyeing – Schoeller was also the first to achieve vivid colours and pure white dyeing on wool without the use of aggressive chemicals, previously considered nearly impossible.

bluesign® APPROVED – Certification for a Sustainable Future

bluesign® is one of the world’s most stringent standards for ecological and safe textile production. The bluesign® APPROVED certification guarantees:

• Minimal environmental impact throughout the entire production chain – from raw material to finished product,

• Safe and non-toxic material composition,

• Protection of workers, consumers, and the environment.

KAMA’s partnership with Schoeller reflects a deep commitment to responsible business practices, without compromising on quality, performance, or environmental values.

Since 1996, KAMA has exclusively processed yarns from Schoeller the Spinning Group. Schoeller is an innovative manufacturer with a number of firsts in its field – it was the first spinning mill in the world to offer under the EXP label wool yarns with chlorine-free wool treatment for washing, meeting the world's strictest ecological standard bluesign® and was also the first in the world to master the dyeing of para-aramids and meta-aramids after spinning or dyeing bright colors and pure (laundry) white on wool!
