It’s all about the Micron!



What makes Woolx® so ultra-soft and luxurious? Our tiny Microns do!

We’re often asked how we make 100% wool garments that are so soft and comfortable. Natural sheep’s wool has been the gold standard in cold weather gear for 100’s of years, but for most of that time it was itchy, scratchy, and downright uncomfortable. Serious outdoor adventurers who required the unparalleled insulating properties of wool put up with itchy arms and scratchy heads to stave off the effects of hypothermia and frostbite. But now there’s no need to sacrifice comfort for warmth, our Woolx® Merino Wool gear is the softest layer you’ll ever wear!


But how do we do it? Well, it’s all about the micron! The extra smooth fibers of the wool from Merino sheep have given us a fabric that feels as soft and comfortable as silk or cashmere, but performs like old school wool.


A Micron is the measurement used to describe the diameter of a wool fiber. The smaller the Micron measurement, the finer and softer the wool. The finest gauge wool comes from Merino sheep, all Merino wool is considered Very Fine, meaning that the fibers are smaller than 24 Microns in diameter. To give you an idea of how small that is, a human hair is on average around 100 Microns wide!

At Woolx® we go even further and use only Australian Merino Wool classified as Superfine. 18.5 Microns for our midweights and heavyweights, and an even softer 17.5 Micron wool for the lightweights.

Superfine Merino wool is as fine as cashmere, providing the softest material possible right next to your skin. These ultra slim fibers won’t poke or scratch, creating the perfect insulating fabric that feels as good as it performs!  Thanks to the tiny Micron fibers in 100% Merino Woolx® you can have a base layer that is naturally breathable, exceptionally warm and incredibly soft. The ideal fabric to wear right next to your most delicate skin!
