Siopor, what’s it all about?

Siopor

“Good things come to those who sweat”, a turn of phrase that may seem a bit of a cliché, but that contains a grain of truth. Nevertheless for people in a nicely heated fitness studio with the prospect of a refreshing shower it may be fashionable to have sweat dripping down your body, but if you’re working for hours in wind and driving rain it’s much less pleasant to be drowning in sweat. That’s why Sioen developed Siopor®, a technical fabric that protects you from all weather conditions — wind, cold & rain — without sealing heat and moisture in.

breathable protection layer that expulses excessive heat and perspiration keeping your hard working body cool and comfortable. The Siopor® range comprises a careful selection of different outer fabrics with a specially adapted coating. Discover all of our Siopor® qualities in the paragraph of the same name.

How does SIOPOR work

Technology

Siopor® consists of a water repellent polyester outer layer with a hydrophilic polyurethane coating on the inside. The breathability of the fabric is assured by the specific structure of the coating. The microporous basecoat has millions of microscopic “canals”. These pores are a thousand times smaller than waterdrops, but considerably larger than moisture vapour molecules allowing them to evaporate.

An additional hydrophilic PU coating transports the moisture vapour molecules to the outside of the garment in a molecular chemical way under the influence of an energy difference (temperature, moisture) between the inside and the outside of the garment. The fabric “breathes”, perspiration can escape.

The outer polyester fabric receives a durable water and dirt/oil repellent finish, so it doesn’t get soaked and stays clean longer. The seams of all Siopor® garments are taped with the most advanced technology.

This technology guarantees the following characteristics:

  • Wind- and waterproof
  • Breathable
  • Comfortable
  • Supple
  • Lightweight
  • Strong
  • Machine washable

The SIOPOR® Experience

Throw on your Siopor® garment and get an early start at work. On a cold and fickle morning you’ll be glad to wrap up warm in the comfy material. And although it offers you warmth and protection, the Siopor® jacket is remarkably light and supple, following your every move. When the rains starts pouring down, you know you needn’t worry. Your Siopor® protection layer will keep you perfectly dry. The durable water repellent finish makes sure the fabric doesn’t absorb the raindrops, so you don’t have to carry the extra weight of the water.

Albeit the cold outside, the work effort heats up your body and perspiration is produced. But before it can start prickling on your skin, your breathing Siopor® layer moves the perspiration away to the outside of the garment where it can evaporate. You can work all day long without having that clammy feeling creeping up on you.
