Look at this majestic beast. Meet Ovis aries, commonly called the merino sheep. After centuries of cross-breeding, this adorable animal produces one of the most versatile and beloved materials in outdoor apparel. Let’s take a little tour of the origins of Merino wool, its unique properties, and some top picks from Decathlon that showcase this natural fiber’s incredible benefits.

Where is Merino wool from?

The Merino sheep, a breed prized for its fine and luxurious fleece, evolved in Spain during the Middle Ages. Merino sheep were closely guarded by Spanish royalty, out of reverence for the high-quality wool. This breed finally appeared in other regions, including Australia and the United States, during the early 1800s. Merino wool production quickly expanded from there, leading to worldwide popularity. Fun fact: Each merino sheep produces 14 to 18 pounds of fleece every season.

Why Merino wool is popular with athletes and hikers

Anyone familiar with sports, camping, or other outdoor activities can attest to the remarkable properties of merino wool. Here’s how Merino wool outperforms other athletic fabrics.

Softness. Unlike traditional wool, Merino wool is exceptionally soft, lightweight, and breathable, making it ideal for itch-free physical activity.

Temperature regulation. Merino wool’s natural moisture-wicking ability helps regulate body temperature, keeping you dry and comfortable in most conditions.

Odor resistance. No stinky sheep here! Merino wool is naturally odor-resistant, so you stay fresh and odor-free even after strenuous adventuring.

Versatile insulation. Merino wool is highly versatile, offering excellent insulation in cold weather and ample cooling in warm weather.

Long-lasting performance. The natural elasticity and durability of Merino wool ensure that your clothes last longer.
