Solid and long-lasting, very practical and indifferent to changes in temperature, the pilus are the ideal partner for gliding serenely towards happiness. The Ultra Light membrane provides a weight reduction even more important than the Super Light and also reduces its volume. This skin is perfectly adapted to our lightest models : vastus, ova et orb freebird. Hybrid composition (Mohair/Nylon): best ratio between climbing grip and glide downhill + high durability. New construction with the first hydrophobic treatment (without fluor): chemical components reduction which does not affect performance while reducing its environmental impact.
