    This keeps my curls in and so healthy—so many other bonnets I’ve tried have fallen off at night, and the pillowcase just doesn’t work for me. This is so cute and stylish

    Lauren - New York

    Amazing sleep mask! High quality materials that feel amazing. Excellent customer service! Recommend 100%!

    Frederick - North Carolina

    A huge difference in skin and hair. Glad I got them and will continue using them for ever.

    Ana - Florida

    I genuinely love this pillowcase. It has drastically helped my acne-prone skin in a matter of weeks, after years of trying to target other areas (diet, skincare, sleep).

    Emma - Massachusetts

    I didn't want to buy a cheap product but I was hesitant at the cost, but am 100% satisfied! I could tell the difference after one night and my hair feels amazing. My hair is now super soft and easy to comb through.

    Snow - Minnesota

    This is everything that I ever wanted in an eye mask. The silk is super soft and feels luxurious (as it should for the price). It fits comfortably around my head, just tight enough to hold on during the night but not enough to feel uncomfortable.

    Rachel - California

    Gorgeous sleep mask and another luxurious unboxing! I now have 4 Clementine sleep masks in my rotation and so happy! They fit beautifully and the feeling I have from an elevated sleep routine with these is SO lovely!

    Michelle - Florida

    Game changer! Love the set option and my curls are so much intact and hydrated in the am.

    Paola - California

    Sofest, most angelic pillow case I've ever laid my head on. The fact the fabric is organic makes a huge difference compared to silk brands that aren't organic. Clementine is the softest!

    Elizabeth - Connecticut

    CLEMENTINE & SUSTAINABILITY

    OUR SILK

    GLOW IN THE NIGHT

    Nothing compares to silk but not all silk is created equal. Cheap blends and chemical washes can do more harm to your skin health than good. And you deserve better. Clementine sleepwear is organic luxury for your skin, hair, and body. Our 100% organic mulberry silk and non toxic dyes hit different. Free of additives and chemicals, the result is a softer and more breathable silk that retains its shine. Your skin and hair will feel fresher for it with no breakouts, rashes, or reactions.
