Billie Eilish is known for her always on-point fashion choices, and her latest face mask doesn't disappoint. On Monday, the young singer posted a picture of herself to her Instagram stories showcasing her newly dyed blonde hair and a mask from Everlane's philanthropic 100% Human line.

The masks come in a pack of five and are made from double-layered woven fabric that features elastic ear loops with a touch of stretch for a lot of comfort — and part of the proceeds go to a very important cause.

"We launched 100% Human as a way to bring people together amid the civil divisions following the 2016 election and advocate for the human rights of all," says the Everlane website. "For every 100% Human product sold, we’re proud to donate 10% to the ACLU, which has been fighting tirelessly to protect our fundamental freedoms for the past 100 years. To date, we’ve donated over $1 million—and we’re not stopping anytime soon."

Billie has been an outspoken advocate for social justice on her social media, so supporting a brand that gives back to a worthwhile charity is on-brand for her.

She's not the only one loving these masks - here's what Everlane customers say about the piece:

"The masks fit both my husband and myself very well," said one customer. "They can easily be layered with a disposable mask underneath for extra protection. I almost forget I’m wearing a mask!"

"These masks are my new favourites. Not only for the colours, but for the comfort," said another. "Soft straps, stretchy cotton knit so I can easily pull them on and off without a lot of fussing, and they cover my face well yet I can still talk without having to readjust them. I joked with my friends, they are like getting comfy new underwear, so nice!"
