Details

Woolen base layers are designed to be worn next to the skin, providing user comfort by maintaining body temperature and controlling moisture. They are highly wicking (will spread moisture out over a large area), fast drying and breathable. It is therefore essential to maintain these properties when caring for woolen base layers.

Base layers are fantastic for regulating your temperature and controlling body moisture, but to keep them functioning properly care must be taken when washing. It is recommended to wash woolen items in mild liquid detergents and to avoid using powder or bio detergents, which contain enzymes. Using conventional household detergents or fabric softeners can impair wicking properties by causing the fabric to retain moisture. This leads to reduced wicking capabilities and slow drying of the fabric, resulting in reduced user comfort. Additionally, standard household softeners can lead to pilling over a number of washes.

All active people should use base layers to effectively manage body moisture and regulate temperature. Hill walkers, runners, cyclists, and mountaineers are among those who utilize base layers to maintain their comfort whilst active.

Once your base layer has been used a few times wash it with Nikwax Wool Wash™ to refresh, remove odors, soften and enhance drying and cooling. Always apply Nikwax Wool Wash™ to used woolen base layers, socks and travel clothing to keep them in perfect condition.

Using conventional household detergents and fabric softeners will impair the wicking properties of base layer fabrics. Standard household detergents do not stop odors from building up in the fabric when in use. Conventional fabric softeners leave water-hating (hydrophobic) residues that will reduce the performance of the fabric, preventing it from spreading moisture and working to its maximum potential. Nikwax Wool Wash™ outperforms conventional household detergents and fabric conditioners at improving wicking, accelerating drying, and removing and preventing odor build up.

Nikwax Wool Wash™ has been specifically formulated for use when cleaning and conditioning woolen base layers. If you have synthetic base layers make sure you use Nikwax BaseWash® for best results.

Benefits of Merino Wool

Moisture Wicking
Merino wool is the best fiber to regulate moisture. It does this by absorbing sweat from your skin and releasing it into the air. Whether you're hiking, running, biking, on the job, or just relaxing at home, our wool helps keep you dry and comfortable all day long.

Soft & Comfortable
Merino wool fibers are much finer than traditional wool, creating a luxuriously soft feel that won’t itch or irritate your skin. Comfortable enough for everyday wear and gentle enough for sensitive skin, it’s a natural choice for underwear, base layers and next-to-skin comfort.

Highly Breathable
Merino wool’s unique structure allows air to circulate freely, helping to regulate your body temperature in both hot and cold weather conditions. Whether you're layering up for winter or staying cool in summer, Merino keeps you comfortable by letting your skin breathe.

Anti-Microbial
Merino wool naturally resists odor-causing bacteria, keeping you fresher for longer. No lingering smells, even after extended wear. Perfect for travel, outdoor adventures, and everyday life.

Insulates When Wet
Merino wool can hold up to 30% of its weight in moisture without feeling wet or clammy against the skin. Unlike cotton or synthetic fabrics, it keeps insulating when damp, making it a smart choice for unpredictable weather and high-output activity.

Fire Resistant
Merino wool is naturally fire-resistant and self-extinguishing. It will not melt or stick to your skin like synthetic fabrics. A trusted option for first responders, campfire safety, or any high-heat environment.

UV Protection
Our Merino wool clothing helps protect you from the sun’s harmful rays, with different levels of UPF based on fabric weight:

• Microweight (145 GSM): UPF 20

• Lightweight (170 GSM): UPF 25

• Midweight (235 GSM): UPF 50+

• Heavyweight (400 GSM): UPF 50+
  

These natural UV-blocking properties make Merino wool ideal for long days or the beach or above treeline.

Renewable and Sustainable
Merino wool is a natural, biodegradable fiber with a low environmental footprint. Grown by Australian Merino sheep and shorn seasonally, it is a renewable material that supports responsible farming practices.
