EASY CARE

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

machine-washable-merino.svg

Machine wash cold inside out and Tumble dry low.

no-fabric-softener.svg

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

Say hello to elevated comfort. 

The Millie takes everything you love about our Layla and loosens things up for a more relaxed, draped silhouette. 

Made from buttery-soft merino wool, it stays breathable, fresh, and endlessly wearable all year round. 

The longer sleeves and easy fit make it a dream for layering or lounging—this is the kind of staple you’ll want in every color. 

Dress it up or keep it casual—either way, it brings softness and style to your everyday.

Style #X230

This top is a loose fit. We recommend purchasing your normal size. 

If you desire a tighter fit, size down by one.
