SHOP SATEEN >> BENEFITS THE SCIENCE REVIEWS SLEEP COOLER TENCEL™️ Lyocell is an advanced fiber made from a sustainably sourced wood pulp from Eucalyptus and other trees. We choose to incorporate this textile innovation into our sheets for its many comfort and wellness benefits. ➀ TEMPERATURE REGULATING The hydrophilic (water absorbing) nature of TENCEL™️ Lyocell means that its fibers absorb moisture more efficiently than cotton. This supports your body’s thermal regulating mechanism, keeping your skin feeling dry and cool all night long. ➁ SKIN FRIENDLY TENCEL™️ fibers are naturally soft to the touch and offer long-lasting comfort. Even when viewed under an electron microscope, the fibers exhibit a smooth surface - which translates to exceptional comfort and softness for even the most sensitive skin. ➀ TEMPERATURE REGULATING The hydrophilic (water absorbing) nature of TENCEL™️ Lyocell means that its fibers absorb moisture more efficiently than cotton.

The production process is an environmentally responsible closed-loop process where nearly 100% of the water used is recovered. ➂ UNFAVORABLE FOR BACTERIAL GROWTH The hydrophilic nature of TENCEL™️ fibers absorb moisture more efficiently and thus there is less available moisture formed on the surface for bacteria to grow versus more common fabrics. ➃ ECO-FRIENDLY TENCEL™️ Lyocell fibers are derived from sustainable wood sources and harvested from certified and controlled sources.

SLEEP BETTER ON MOLECULE >> YOUR SLEEP STAGES In any given night of sleep, your body typically goes through four distinct stages of sleep. One stage in particular, Slow Wave Sleep (N3), is the most restorative stage for your body. ✓ Deepest stage of sleep and the hardest to wake up from ✓ Blood pressure drops ✓ Breathing becomes slower, deeper, more rhythmic BENEFITS OF SLOW WAVE SLEEP During this most restorative stage of sleep (which typically represents 25% of the night), the following recovery-focused functions occur: WHAT HAPPENS BENEFIT Your brain is resting so the blood supply to your muscles increases ➜ More nutrients available for muscle and tissue repair Your pituitary gland releases human growth hormone (HGH) ➜ Stimulates cell regeneration essential for growth and muscle development Your body releases prolactin ➜ Aids in joint recovery Your body releases appetite control hormones ➜ Helps maintain a healthy weight Your body regulates cortisol (the stress hormone) ➜ Helps your body's ability to digest glucose, which is directly tied to endurance HOW MOLECULE SHEETS HELP Getting sufficient Slow Wave Sleep is critical for anyone who wants to maximize their body recovery and performance. One of the most important factors that can influence the quality and duration of your body’s recovery during sleep is an adequate drop in your core body temperature. Our body’s thermoregulation is less efficient during sleep, so external controllable factors that affect temperature - such as the products you sleep on - are essential. At MOLECULE, we develop products designed to maximize airflow and facilitate cooling to help people rest and recover during the night so they can maximize their performance during the day. Our R&D team and Medical Advisory board select materials, invent production processes, and use cutting-edge sleep technology solutions to create products that efficiently transfer heat away from the body - an important factor to getting the most restorative sleep possible. The result? Unmatched innovation through sleep products that keep you cool and optimize your sleep and recovery. ★★★★★ Jane B. ✓ Verified Buyer My husband usually sleeps hot, but he said that with these sheets he doesn’t get as hot. The fabric is soft, smooth, and breathable. Customer service is excellent. If you are looking for crisp breathable sheets, the percale is a great choice. ★★★★★ Christopher C. ✓ Verified Buyer Unbelievably comfortable and my wife and I stayed COOL all night long. This is a first for the both of us in over 2 years.100% RECOMMEND Molecule Sateen Sheets! ★★★★★ Esther A. ✓ Verified Buyer I was really pleasantly surprised by how soft and light these sheets are. I buy sheets all the time and am rarely really pleased. I will get these again and also intend to gift them to my kids. ★★★★★ Stephen G. ✓ Verified Buyer Amazingly, these sheets work as advertised. I had grown accustomed to waking in the middle of the night to the feeling of clinging, sweaty sheets and pillow. Pretty gross. I honestly didn’t think this was fixable with sheets, but it was! I am not sure if these sheets are cooler and I sweat less, or if they handle the moisture differently, but I am no longer waking with that same feeling. A very nice change, and worth the expense. ★★★★★ Jim B. ✓ Verified Buyer Love these percale sheets! I tend to be too warm in bed at night, and at times have woken up in a sweat. I have had totally comfortable nights since using these Molecule percale sheets. I bought them out of curiosity. I bought a second set after sleeping on the first set I bought! I’m a believer! ★★★★★ Jamie N. ✓ Verified Buyer These sheets are amazing! My fiancé gets hot when he sleeps and we have tried so many very expensive sheets we ended up being disappointed with. These stay cool all night long and feel so soft on your skin! Highly recommend!
