Stops Your Pillowcase From Absorbing Your Skincare Products Reduces Morning Frizz, Tangles & Hair Breakage Keeps Your Pillow Cool All Night So You Stop Flipping It Helps Reduce Breakouts Caused By Bacteria On Cotton Pillowcases A Fraction Of The Cost Of Real Silk Pillowcases   ## Recommended by Sleep Experts _"Just what the doctor ordered and I'm thrilled about finally getting these cooling pillowcases which are antibacterial and 100% vegan which is good for your skin and hair.”_ - **Kamar B.** **Verified Buyer** ## GET A FULL NIGHT’S REST ## Wake Up Looking & Feeling Rested! Standard pillowcases (even the "nice" ones) are made of cotton fibers that grab onto your skin as you move in your sleep. That friction is what causes sleep creases. And while all that friction is happening, your cotton pillowcase is soaking up the serum you applied before bed, the moisturizer you paid $60 for, the face oil that is supposed to work overnight. When you switch to Mellow, everything changes on night one. **The silk-like surface glides against your skin instead of grabbing it.** Sleep creases disappear. Your skincare products stay where you put them. And because of the cooling fiber technology built into every pillowcase, you stop flipping your pillow at 2 AM looking for the cool side.   ## FOR BEAUTY AND HOT SLEEPERS ## Perfect For Every Type of Sleeper Mellow always feels cool and smooth against your face, no matter how you sleep or how many times you toss and turn at night. 1. **Hot Sleeper —** Instantly draws heart away on contact. Keeping your pillow cool and dry while you sleep for a refreshing night’s rest. 2. **Beauty Sleeper —** The same smooth surface lets your hair move freely while you sleep instead of snagging and pulling against rough cotton fibers, so you wake up with less frizz, fewer tangles, and noticeably less breakage over time. **Finally wake up with smoother skin, healthier hair, and a pillow that actually stays cool all night.**  ## LUXURY YOU CAN TRUST ## Silk-Like Softness + Cooling Technology For the first time ever, you don’t have to choose between a pillowcase that’s good for your skin and hair, and one that keeps you cool. Unlike other pillowcases that use cheap coatings that wash out, FrostWeave™ is a proprietary cooling fiber woven directly into the fabric. This creates **a cool-to-the-touch surface that actively pulls heat away from your body,** so you stay comfortable all night long. But it’s not just about cooling. The weave is incredibly fine and smooth. This allows your skin and hair to glide across the surface, instead of catching and tugging.

The FrostWeave (™) isn't just soft fabric with a nice name. It's a purposeful combination of cooling fiber technology and a friction-free surface that has been designed to deliver real, visible results by morning. ## This is what beauty sleep is supposed to feel like. ## **Your Satisfaction is Our Priority** ## Try Mellow Hotel Pillow risk-free and if you don’t love it, we’ll fix it.  30-NIGHT BETTER SLEEP GUARANTEE Try Mellow Cooling Pillowcases yourself for up to 30 nights, and if you aren’t 100% satisfied, simply return it!  1-YEAR WARRANTY Each Mellow Cooling Pillowcase is proudly backed by a 1-year warranty.

Item type: White / Standard  +3 Tracy M.Verified 9/23/2026 Unbelievable. I hesitated to write a review because I want to give a lot of these products as Christmas gifts, and I don't want them to run out. These photos show the Puff Pillows (in blue) on my bed, as well as the Plouf Pillow in front. I encase my Plouf Pillow in a cooling slipcase from Mellow.
