What is 100% Merino Wool Jersey Fabric? Superfine merino wool jersey is a soft, breathable, and odour-resistant fabric that helps regulate your body temperature in both warm and cool weather. Its fibres are much finer than regular wool, measuring 17.5 to 18.5 microns, so it feels smooth and comfortable, even for sensitive skin. We offer two weights: 150 gsm and 200 gsm. What are the benefits of superfine merino wool? Superior comfort and softness: Unlike coarse wool, superfine merino has smaller fibres that bend easily against your skin and do not cause irritation. Temperature regulation: It naturally keeps you cool in summer by wicking away moisture and warm in winter by holding in heat. Odour resistance: The natural fibres help prevent odours, so you can wear your clothes several times before washing. This is great for travel or hiking. Moisture management: Merino wool absorbs and releases moisture, helping you keep dry even when you are active. Comfort for sensitive skin: Many people with sensitive skin find superfine merino more comfortable than synthetic or cotton fabrics. Some studies also suggest it may help improve sleep quality. Natural protection: Merino offers inherent UV resistance and is typically less prone to static than synthetic fabrics. How do I care for merino wool jersey fabric? We recommend washing in cool water and hanging to dry. Some customers hand-wash their merino t-shirts in a hotel sink, squeeze them in a towel, and let them dry in about four hours, which is very convenient for travel. What can I make with merino wool jersey? Merino wool is a great option for long underwear and base layers because it resists odours and helps regulate temperature.
