How it works

How StayCool works

Traditional fabrics can trap heat and moisture, creating discomfort during training, work, sleep, or hot weather. Polygiene StayCool™‎ supports a cooling sensation by helping the textile respond to moisture and heat — improving the comfort experience while the fabric is in use.

Depending on the fabric, application and testing route, StayCool may support a measurable cooling effect and improved perceived comfort — evaluated as part of the technical sample process.

FAQ

Questions, answered.

It supports a cooling comfort effect by helping the textile respond to heat and moisture during use.

In sport, activewear, hot climates, long shifts, towels, bedding, and products where heat and comfort matter.

Towels — especially sports, performance and bath towels — are among the applications StayCool is intended for, but StayCool is still in development and is not yet part of INATURAL products.

That is the plan once StayCool completes development: it is designed to be combined with freshness and odour-control technologies, depending on the textile category and production goals.

Cooling comfort evaluation, wash durability and application-specific testing can be discussed during the sample and technical dossier process.
