Why Thermo Fleece®?
Thermo Fleece® woolen underwear keeps you warm as toast in the coldest conditions without ever feeling clammy – even if you’re wearing rainproof clothing over the top! Thermo Fleece® merino woolen underwear offers the very best in quality, it’s knitted from 100% pure super soft wool from Australian Merino sheep.
Developed after years of research, Australian super soft Merino wool is blissfully comfortable and prickle free against the skin, yet it’s incredibly easy to care for – the unique double knit interlock and pointelle pattern knit fabric guarantees long wear and no shrinkage and you can even machine wash it. All garments are also “side seam-free” for supreme comfort. Try Thermo Fleece® woolen underwear and enjoy the difference.
100% Merino
Only 100% Merino is best.
When another fiber is blended with merino wool is it primarily for one reason and one reason only – cost!
Other fibers are significantly cheaper than merino wool.
You may have noticed many brands now advertise as “Merino” but when you look closely, they are actually a blend (some call it fusion) of Merino and other inferior fibers such as polyester, modal, acrylic, nylon, elastane, spandex and other marketing terms. These synthetic fibers they add are approximately 80% cheaper than merino wool, a clever way to bulk up the fabric with second rate fillers and hope no one notices the difference.
Merino Skins® base layers are made from 100% Merino wool.
The Merino wool we use in Merino Skins® isn’t just any old Merino wool either. We carefully select non mulesed superfine merino wool from local farms here in Australia that have long fiber lengths to ensure the garments are itch-free, soft and comfortable against the skin.
Don’t be fooled, read the fabric contents carefully before you buy, don’t compromise with inferior “Merino” blends disguised as pure Merino, only buy 100% Merino – natures miracle fiber.
Easy Care
Merino Skins® base layers are 100% easy care.
Unlike many other brands of Merino base layers that are hand wash and line dry only, Merino Skins are fully machine washable and tumble dryable.
Due to our unique double knit interlock fabric construction together with our fabric being preshrunk before sewing Merino Skins® are truly easy care – machine wash and tumble dryable.
You don’t have to worry, just throw them in the machine (please read washing instructions) and they come out looking fantastic every time.

Verified ownerReally nice base layer piece. Stitching and fabric seem to be of very high quality. Adds a lot of warmth for the core without restricting movement. Plan to use for cycling, nordic skiing, and general outdoor use in cold temperatures. I’m 6’0″ (183 cm), 162 lbs (74 kg), and a Medium fits very closely without being tight.
Verified ownerHighly recommend! I was searching for a high-quality Merino Wool base layer that wasn’t made in China, and after lots of research, I came across Merino Skins. I ordered from UK. They offered a great service, and my parcel arrived quickly. Excellent quality garment.
Verified ownerIt took me a long time to find you, but henceforth …
Verified ownerSkins describes how warm soft and comfortable these long john underwear are. Quality is definitely there.
Verified ownerI liked the snug fit. Washed well. Lace is a little high up and shows under some tops nice and cozy.
