What is Lycra and what are its properties?
Lycra is a revolutionary synthetic fiber made from polyurethane, invented by the American company DuPont in 1958. This material stands out for its exceptional elasticity—it can stretch up to seven times its original length and instantly return to its initial shape when released.
Lycra and other fabrics
Lycra fabric is never used alone—it’s always blended with other fibers such as cotton, polyester, or nylon, usually in proportions of 2% to 15%. This hybrid composition transformed the textile industry by adding comfort and freedom of movement to clothing.
Lycra: a must-have for surfing
Its technical properties make it an ideal choice for swimwear and surf suits: resistance to chlorine and salt, UV protection, quick drying, and breathability. Lycra resists bacteria and mold while retaining its shape even after multiple stretches.
Why use Lycra in sportswear?
When you practice your favorite sport, your outfit must move freely with your body. Lycra transforms your athletic experience by offering total freedom of movement—no more garments that pull or lose shape during effort.
This fiber provides optimal support without excessive compression, perfect for endurance sports such as hiking or trail running. Your muscles enjoy light support that improves blood circulation and reduces fatigue.
Quick drying is another big advantage during outdoor activities: moisture is effectively wicked away, keeping you comfortable even in humid conditions. Brands like Picture use Lycra in their technical collections to ensure lasting performance, session after session.
What’s the difference between Lycra and other fibers (spandex, polyester, neoprene)?
Lycra vs. Spandex (or Elastane): a matter of branding
Lycra and elastane refer to the exact same polyurethane-based synthetic fiber. The confusion comes from the fact that Lycra® is a registered trademark created by DuPont in 1962, while elastane is the generic name used in Europe.
Spandex is simply the English term for elastane. All three terms often appear on clothing labels, but they refer to the same material.
The real difference lies in quality—Lycra® fibers are subject to stricter quality controls and generally maintain their elasticity better over time compared to cheaper generic elastanes.
Lycra vs. Polyester: elasticity vs. durability
Lycra is all about elasticity: it stretches up to seven times its length and instantly snaps back. This flexibility makes it ideal for dynamic movement and form-fitting garments.
Polyester, on the other hand, prioritizes durability and abrasion resistance. Its fibers handle friction and wear better and keep their appearance longer, although they offer less natural stretch.
Your choice depends on your priorities: Lycra for comfort and freedom of movement in dynamic activities, polyester for long-lasting resistance under tough conditions. Polyester-Lycra blends combine both benefits, with proportions adjusted for the intended use.
Lycra vs. Neoprene: flexibility or thermal insulation
If you’re choosing between a Lycra top and a neoprene one for water sessions, water temperature will guide your decision. Lycra excels in flexibility and freedom of movement, perfect for warm waters where UV protection and comfort are your main goals.
Neoprene, made of closed air-filled cells, focuses on thermal insulation. The thicker it is, the better it retains body heat—but flexibility decreases as thickness increases. Ultra-stretch neoprenes remain comfortable even at higher thicknesses.
Some hybrid designs, such as those from Picture, combine Lycra sleeves for mobility and neoprene torsos for warmth—offering flexible shoulders and thermal protection for the chest.
How to choose your Lycra fabrics?
The best Lycra blend depends primarily on your sport. For water activities, choose a nylon-Lycra mix—it’s more resistant to chlorine and salt. For land sports, polyester-Lycra blends are more durable against friction.
Always check the Lycra percentage:
15–20% for firm support (compression, cycling)
5–10% for more flexibility (yoga, hiking)
A high-quality Lycra fabric returns to its shape after stretching without visible deformation.
