Introduction to the
knitwear fabric families
The knitwear fabrics in the Sioen PRO range are designed to be worn close to the skin as the first protective layer. They combine moisture management, thermal regulation and comfort, ensuring that workers stay dry, warm or cool depending on the conditions.
Knitwear fabric groups in the picture
These four groups illustrate the diversity of our knitwear fabrics, but the range includes other specialised options as well:
SIO-DRY
Fresh & dry performance with added warmth options
SIO-DRY® fabrics are designed to keep the body fresh and dry. Thanks to the use of polypropylene, they quickly transport perspiration away from the skin, helping to prevent chill and discomfort during physical activity. In addition to the light, moisture-wicking versions, the fleece variants provide warmth while maintaining a dry feeling, making them suitable for both active work and cold environments.
Polypropylene: fresh & dry bodywear
Fleece: warm & dry bodywear
BASIC LINE
Lightweight bird-eye structure for quick-drying performance
The BASIC LINE fabrics are built from 100% polyester in a bird-eye knit structure. This makes them lightweight (± 140 g/m²), breathable and fast-drying, ensuring comfort during long working days. BASIC LINE is a practical, cost-effective choice for functional bodywear.

SIO-COOL
Breathable, stretchable and UV-protective bodywear
SIO-COOL® fabrics are engineered to deliver cooling comfort and protection against the sun. With versions ranging from highly breathable to very stretchable, they adapt to the body and support freedom of movement. All variants provide UV protection, making them especially suitable for outdoor work in warm climates.
When to use these fabrics
Knitwear fabrics are the foundation of a proper protective clothing system. As base layers, they are worn directly against the skin to regulate body temperature, wick away moisture and add extra comfort. Whether you need fresh and dry bodywear under heavy protective garments, quick-drying performance layers for active work, or breathable tops with UV protection in warm conditions, the knitwear families provide the right solution for every environment.
