Traditional Wool vs Merino wool

Wool has been around for many, many years. It’s always had the magical benefits of keeping you warm in the Winter and cool in the Summer. But, it was scratchy. Stiff. Now, brands like SmartWool have entered the space with Merino wool, changing how outdoor enthusiasts and active people think of wool clothing.

What’s great about Merino wool activewear

Merino wool clothing is great for outdoor workouts, because it’s natural fiber that performs like a performance synthetic. That’s why Merino can be used for clothing items– baselayers, jackets, even undergarments.

How to wash Merino wool


1 Check tags, turn clothes inside out

Not all Merino wool items are exactly the same. Check the manufacturer’s care instructions for details, like whether the item can be dried in the machine or should be laid flat to dry.

2 Wash with HEX and cool water

Use HEX Detergent for the best fabric care. It’s actually designed with fabric technology in mind. And unlike traditional detergents, HEX works on natural fibers just as well as synthetics and blends. Do not add bleach or traditional fabric softeners when washing Merino wool. Wash on a gentle cycle with cold water (or as otherwise specified on the care tag instructions). Air drying or tumble drying on low is recommended for most wool clothing.

What’s wrong with using fabric softener on Merino wool clothing?

Check the tag, and you’ll likely see “do not use softeners.” That’s because fabric softeners are known to coat fabrics, which is bad news for technical features like sweat-wicking. Traditional fabric softeners were built before modern activewear and outdoors clothing became so advanced.
