EASY CARE

Follow these tips for the best performance and longest life for your garment:

Machine wash cold inside out and Tumble dry low.

Avoid fabric softener. Though it won't damage the clothing it does coat the fibers in a wax that neutralizes many benefits of Merino.

The Millie is the long sleeve that feels like a favorite from day one. 

Made from breathable, odor-resistant merino wool, it keeps you comfortable whether you’re layering up or wearing it solo. 

Its relaxed fit, longer short sleeves, and flattering neckline strike the perfect balance between cozy and chic—perfect for travel days, work-from-home days, and everything in between.
