Flexothane Waterproof Clothing

Flexothane Waterproof Clothing by Sioen is a range of waterproof outerwear built from a specialised technical fabric engineered to protect wearers from wind and rain. Sioen applies a high-grade polyurethane coating on a stretchable knitted base to achieve a durable, water- and windproof barrier that performs reliably in wet conditions. Therefore, garments made from Flexothane deliver lasting protection when working outdoors, walking in heavy rain, or facing variable weather conditions.

The core of the Flexothane range lies in its fabric technology. Sioen developed the Flexothane material so that it remains strong and tear-resistant while still remaining supple and flexible. Consequently, wearers maintain freedom of movement without feeling restricted when bending, lifting, or walking for long periods. In addition, the knitted base absorbs perspiration and supports breathability, which helps prevent a clammy feeling while active. Because the fabric stretches up to approximately 150 %, it adapts to movement and resists damage during regular use.

Flexothane garments include waterproof jackets, trousers, bib and brace overalls, coveralls, bodywarmers, aprons, capes, and accessories designed for protection across different work and outdoor scenarios. Many items feature high-frequency welded seams, which help maintain reliable waterproofing at all points of construction. Therefore, wearers can count on consistent protection even in heavy rain or sustained weather exposure.

Sioen engineers the Flexothane range to resist common contaminants encountered outdoors, including oil, fuel, diesel, and grease. The smooth polyurethane surface repels moisture and allows easy cleaning after a long day of work or outdoor activity. Furthermore, the material supports machine washing, which simplifies maintenance and prolongs garment life.

The Flexothane range offers variants tailored to different needs. Some garments prioritise everyday waterproof protection with lightweight comfort, while others add high visibility features or specific functional enhancements. Because Sioen produces Flexothane fabric and garments in integrated facilities, the company maintains quality control from material development to finished product. Flexothane garments therefore combine technical performance with practical design, making them suitable for outdoor work, professional use, and recreational protection from wet weather.
