September 12, 2024 | icebreaker

As consumers become more eco-conscious, the demand for sustainable fashion is on the rise. Natural wool clothing, particularly merino wool, has emerged as a leading choice for those seeking comfort, performance, and environmental responsibility. At icebreaker, we are committed to harnessing the power of natural fibers to create high-performance apparel that aligns with our values of sustainability and innovation.

Understanding Natural Wool Fiber

What Are Natural Fiber Clothes?

Natural fiber clothes are made from materials derived from plants and animals. Unlike synthetic fibers, which are produced using petrochemicals, natural fibers are renewable and biodegradable. Examples of natural fibers include cotton, linen, silk, and wool. Wool, particularly Merino wool, is renowned for its unique properties that make it ideal for clothing.


Which Is the Most Widely Used Natural Fiber Clothing?

Wool is one of the most widely used natural fibers in the clothing industry, and merino wool is celebrated for its superior qualities. Merino wool stands out due to its fine fibers, which are softer, more breathable, and less itchy than regular wool. This makes it a preferred choice for a variety of clothing, from base layers to outerwear.


The Benefits of Natural Wool Clothing

Renewable and Sustainable: One of the primary benefits of natural wool clothing is its sustainability. Sheep produce new fleece every year, making wool a renewable resource. At icebreaker, we are dedicated to sustainable farming practices that ensure the animals' welfare and the environment's health. Our commitment to using natural fibers can reduce the outdoor apparel industry’s reliance on synthetic materials derived from non-renewable resources and have a higher environmental impact.


Biodegradability: Wool is naturally biodegradable, meaning it decomposes quickly and returns to the soil without leaving harmful residues. Unlike synthetic fibers like polyester, which showed no degradation over a nine-month period, wool products degrade much faster. For instance, thin, lightweight woven wool fabrics can achieve over 90% biodegradation in just two months, and nearly 100% in nine months. According to a study conducted for the Wool Research Organisation of New Zealand, knitted wool fabrics demonstrated around 36% mass loss after two months and approximately 76-99% mass loss after nine months, whereas polyester knit fabric did not degrade at all during the nine-month burial period of the study.


Comfort and Performance: Wool’s natural properties provide unparalleled comfort and performance. Merino wool is particularly valued for its ability to regulate body temperature, keeping you warm in cold weather and cool in hot weather. The fine fibers create a breathable fabric that allows air to circulate, preventing overheating and ensuring comfort in all conditions. Additionally, wool’s moisture-wicking capabilities draw sweat away from the skin, keeping you dry and comfortable during physical activities.


Health and Hygiene: Merino wool has natural antibacterial properties due to the presence of lanolin, which helps repel bacteria and odors. This makes wool clothing a hygienic choice, especially for activewear and travel. Wool is also hypoallergenic, making it suitable for people with sensitive skin. The natural elasticity of wool fibers allows garments to move with your body, providing a comfortable fit without restricting movement.


Merino Wool: The Superior Natural Fiber

Unique Properties of Merino Wool

Merino wool’s unique properties set it apart from other types of wool. The fine fibers are incredibly soft, making them comfortable to wear next to the skin. Merino wool is also highly breathable and an effective water repellant, ensuring you stay dry and comfortable in various conditions. These qualities make merino wool a versatile choice for outdoor enthusiasts, athletes, and everyday wear.
