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.

Designed as a relaxed version of our best-selling Layla V-Neck, the Millie offers the same incredible softness and performance with a more flowy, easygoing fit. 

Crafted from luxuriously soft merino wool, it drapes beautifully, keeping you comfortable and polished without ever feeling tight or restrictive.

Perfect for layering or wearing on its own, the Millie naturally regulates temperature, wicks moisture, and resists odor, making it the ideal go-to for any season. 

The flattering V-neckline and relaxed silhouette create a timeless, put-together look that pairs seamlessly with jeans, joggers, or even your favorite cozy lounge pants.

With its low-maintenance, easy-care merino wool fabric, the Millie is designed for real life—less washing, more wearing, and a comfort you’ll never want to take off.
