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.
