A few simple Merino wool care steps will keep your Merino socks, base layers, and other clothing looking as great as they feel. Washing Merino wool Smartwool® products is generally okay, but it’s important to check the tag on each garment for best results.
Turn socks and garments inside out.
Machine-wash on gentle cycle in warm or cool water (avoid hot water as heat may shrink wool).
Use mild soap, no bleach or fabric softener (bleach destroys the Merino wool fibers, and fabric softener coats those fibers—reducing their ability to naturally manage moisture and regulate body temperature).
While you can tumble-dry most of our Merino, we recommend air-drying to reduce your environmental impact and further extend the life of each product. Dry your wool clothes by laying them flat (hanging wet wool may distort the shape). If you prefer the dryer, tumble-dry on low setting. And, as always, check the care label. A few of our products still shouldn’t be dried in the dryer.
Some of our jackets and vests contain a DWR (durable water repellent) finish that is great for helping to keep you dry. Over time, dirt and oil accumulation may reduce the effectiveness of DWR, making it less water-repellent. Occasional cleaning will help keep your DWR working efficiently. However, it’s a bit of a balance. The DWR treatment will eventually wash off with repeated laundering and will need to be reapplied.
