What are PFAS?

PFAS are known as "forever chemicals" because they do not break down naturally, accumulating in the environment and the human body over time. This has been linked to lead to hormonal disruption and other health issues.

What IS QMAX?

Qmax measures how cool a fabric feels instantly when it touches your skin. The higher the value, the faster the heat transfers, and the "cooler" the fabric feels.

This measures how long the fabric clings to a surface due to static electricity after being rubbed against another material. It simulates a shirt sticking to your body or pants sticking to your leg.

The Science of Evercool®

Cool-to-the-Touch

Evercool® is a proprietary fabric that instantly cools and regulates your body temperature for all night comfort, making it the best bedding for hot sleepers.

Smooth & Soft

Engineered from ultra-fine, smooth fibers 75x thinner than hair, Evercool® is frictionless and glides effortlessly across your skin.

Moisture-Wicking

Moisture is pulled and evaporates immediately through microscopic channels for uninterrupted, sweat-free sleep.

Breathable

Evercool® is designed to actively release trapped heat while allowing fresh, cool air to circulate throughout the night for optimal thermal regulation.

Antimicrobial

Evercool®+ is permanently 'self-cleaning'; embedded with naturally antimicrobial silver yarn that protects the bedding from odor and bacterial growth.

Rest® Labs

Each Evercool® product undergoes extensive R&D to ensure it’s optimally cool, comfy, and clean.

01 Thermal Conductivity. Evercool’s high-conductivity polyamide yarns outperform fabrics like silk, bamboo and cotton, keeping hot sleepers cool and comfortable.

02 High Contact Fabric Surface. Engineered for a buttery-soft touch that gets even smoother with every wash.

03 Moisture Wicking. By knitting ultra-fine, smooth fibers at high densities, the resulting Evercool® fabric has significantly more surface area that touches your skin. This maximizes heat dispersion and allows for faster sweat wicking.

04 Breathability. Independent airflow testing shows Evercool® is light, airy, and breathable for uninterrupted rest.

How Evercool® Compares

Evercool® outperforms fabrics like silk, bamboo and cotton, keeping hot sleepers cool and comfortable for uninterrupted rest.

FAQs

What makes the Evercool®+ Cooling Flat Sheet different?

The Evercool®+ Cooling Flat Sheet is actually cool, really cool. It has one of the highest lab tested Qmax values on the market at 0.40 (cotton is 0.11 and silk is 0.19). The higher the Qmax value, the higher the cool to the touch effect. The best part is that the Evercool®+ fabric achieves these values without using any cooling additives, nano-particles or chemicals. The sheets also have IONIC+ Antimicrobial Technology woven into the fabric to help prevent microbes from accumulating on the fabric, keeping the sheets fresher and cleaner longer.

What is the Evercool®+ Cooling Flat Sheet made of?

The Silvercool® Sheet Set consists of two main ingredients: A nylon and spandex blend and IONIC+ Antimicrobial Technology silver yarn. The advance nylon used offers the cool to the touch effect, high moisture wicking capability and silky touch. The spandex gives the outer shell a little stretch to improve on the anti-sagging properties and machine washability. IONIC+ Antimicrobial Technology silver yarn is permanent and never washes out. It helps the fabric stay fresher, cleaner, and lasting longer.

Is there a warranty for the Evercool®+ Cooling Flat Sheet?

With our one-year limited warranty on all our products, you're guaranteed high-quality, well made products.

Can I return the Evercool®+ Cooling Flat Sheet if I’m not satisfied?

If you're not satisfied, you can easily return for up to 30 days. To ensure you're getting the best price, we also offer a Rest Easy Best Price Guarantee.

How do I wash and care for the Evercool®+ Cooling Flat Sheet?

Just like other bedding products and clothing, it’s best to wash before use. Wash separately on gentle with a pH neutral detergent. Tumble dry on low or delicate. Do not iron, dry clean, bleach, or use fabric softener.

    I almost returned it within the first hour. Here’s why I didn’t, how it changed my life, and why I ended up buying the entire range

    I have over 20 chronic health conditions including Hashimoto’s, perimenopause, and B12 deficiency- all of which affect my body’s ability to regulate temperature. I run hot constantly, and I’m housebound and bedbound 24/7, so my bed isn’t just somewhere I sleep. It’s where I live.

    I had tried everything. Ecosa’s cooling blanket, cooling pillow overlay, cooling mattress overlay. The Oodie cooling blanket. Every single one followed the same pattern- cold to the touch initially, then warming up over time until they were useless. I’d basically given up on cooling products.

    Then an AI suggested Evercool Rest, specifically because I’d mentioned I was dealing with 80-90% humidity and 21 degree dew points most nights. It explained that “cold to touch” products work by absorbing heat- but in high humidity, that heat has nowhere to go, so the products just warm up. Evercool works differently.

    When it arrived, I was confused. It wasn’t cold to touch. It was room temperature. I was annoyed. I thought I’d wasted my money again.

    But I was told to just put it on my legs and wait.

    After about 45 minutes I noticed something strange — my face was cool. I hadn’t touched my face with the sheet. I started yawning. I fell asleep. When I woke up the next morning, I had subconsciously pulled the sheet all the way up over my shoulders in my sleep. My body knew before my brain did.

    That was January. Since then I have bought the flat sheet in two sizes, the starter sheet set, the cooling…
