Wool Surf Trunks and Wet Suits? Absolutely!

Wool often brings to mind thick, warm, and itchy sweaters. But have you ever imagined wool in swimwear or wetsuits? It’s time to rethink your perception of wool, as it’s now being used in surprising ways, including activewear and gear for water sports.

Specifically, we’re referring to merino wool. This material is sourced from the fleece of merino sheep, which were originally from Spain but are now predominantly found in Australia.

The unique qualities of merino wool stem from its fibers. The wool from merino sheep is fine, durable, and elastic, resulting in garments that are significantly softer than traditional wool fabrics. Additionally, it adapts to your body’s temperature, making it perfect for heavy sweaters.

But how does wool fare in swimwear? Unlike synthetic materials, wool is naturally hygroscopic, meaning it absorbs moisture from the air. A wool bathing suit can absorb up to 35 percent of its weight in water without feeling wet or sticking to your skin, keeping you warm even when drenched. Pretty impressive, right?

This unique property inspired surfing legend Kelly Slater to create his Woolaroo surf trunks, the first modern brand to use 100 percent wool for board shorts. Similarly, the Luna Rossa Prada Pirelli sailing team opted for merino wool for their uniforms during the 2020 America's Cup World Series in Cagliari, Italy. Their gear included waterproof jackets, wetsuits, T-shirts, and base layers, all crafted from wool.

"This marks the first time wool will be used on such a grand scale at sea, showcasing Australian wool in an innovative light," said Stuart McCullough, Managing Director of The Woolmark Company, in a press release. The Woolmark Company, known for its iconic logo, researches, develops, and certifies Australian wool, promoting its use in textiles worldwide.

While wool might not seem like an obvious choice for athletic wear, it outperforms synthetic fabrics in breathability and odor control. Research shows it wicks moisture 30 times more effectively than polyester and manages body odor better than cotton or acrylic. This is why wool socks and base layers are favorites among hikers, runners, skiers, and snowboarders.
