“We already thought a long time ago at Maloja about how functional clothing can stay fresh longer, in order to save valuable resources – for instance through fewer washing cycles. With Polygiene, we found what we were looking for. Almost all tricots and the high-performance chamois in the bike shorts are treated with Polygiene. Especially in the bike sector, the technology can show its full strength – from long road bike rides to multi-day gravel bike-packing tours to MTB alpine crossings”

“At M.M.LaFleur, our mission is to make life easier for professional women by providing them with polished-but-practical workwear options. By partnering with Polygiene and incorporating their anti-odor finish, we’re essentially giving working women the benefits of activewear – they can hustle on their commutes and sit through long meetings without having to worry about smelly garments. The fact that the treatment process is sustainable and environmentally friendly is also incredibly important to us”
Audrey O’Brien Director of Fabric R&D, M.M.LaFleur

Protects against odors for long-lasting freshness

Polygiene StayFresh technology prevents bacteria from growing on fabrics and textiles so they don’t smell. Less odor means less washing, saving water, energy and wear and tear so products last longer and need to be replaced less frequently. With Polygiene StayFresh embedded in your products you move from consumables to durables – it’s a simple way to meet your sustainability targets while passing on highly desirable benefits to your customers.

How does it work?

Polygiene StayFresh is based on silver chloride, a salt that is naturally present in water and soil. The silver ions in the salt make it impossible for the bacteria responsible for bad smells to multiply, stopping odor in its tracks

This advanced technology is integrated into the fabric, so freshness is built-in for the lifetime of the garment. And because it’s added during the finishing stage, there’s no additional energy or water required during the application, minimizing environmental impact during manufacture too.
