The String N°19 by Hastko is technical performance underwear with a true second-skin feel, built for active movement and uncompromising comfort.

Its seamless construction with bonded edges and SENSELAST® Velvet Soft Touch feels soft against the skin and remains nearly invisible under close-fitting activewear. Transparent stretch tulle elements add a feminine lightness without losing the product’s technical focus. Developed by the HÄSTKO team in Chamonix-Mont-Blanc and tested across a wide range of active use, the close fit adapts to the body after the first few wears while maintaining its shape over time.

Fabric:
Main fabric: 75 % polyamide, 25 % elastane

Lining: 98 % cotton, 2 % elastane
