Supertech sodium filled valves made of Inconel/Nimonic alloy offer a significant reduction in valve head temperatures that are required for today’s modern turbo engines.

Valves play a critical role in any performance-orientated engine. Upgrading the valves in your VW or Audi engine increases reliability with slow forging processes, upgraded aerospace alloys, CNC machining, and heat treatments to withstand extreme abuse from high-powered race engines and daily driven road vehicles making beyond factory power levels. The power an engine produces is limited to airflow. As the smallest chokepoint in your cylinder head, performance valves are engineered to increase airflow by limiting turbulence created by valve stem obstruction and careful detailing of the valve head and valve angles.

Perfect Pillow!
Size: Ultra Slim (2.75-Inch Height), Color: Blue
I have spent so much money trying to find the right pillow. As a side sleeper I would always wake up with a stiff neck but not with this pillow! It’s a perfect height and the pillow stays fairly cool. It’s totally my Goldilocks pillow!❤️

Finally a Cooling Blanket That Actually Works for Hot Sleepers
Size: Queen (90" * 90"）, Color: Luxury Grey, Size: Queen (90" * 90"）, Color: Luxury Grey
I first got to know this brand when they released their cooling pillow. At the time, I was very skeptical because I’ve tried many “cooling” pillows and pillowcases from other brands, and almost all of them failed to stay cool throughout the night. Surprisingly, this brand was the first one that actually worked for me.
Going through menopause has been extremely difficult, especially dealing with the constant heat and night sweats. I kept thinking that if they could somehow use the same cooling technology in a blanket, it would be amazing — and they actually did it.
This blanket has honestly been a lifesaver for me. One side has the cooling fabric while the other side feels more like a regular blanket, so you can switch depending on the temperature or season. I’ve been using a silk comforter before this, and while it was comfortable, it really didn’t help much with overheating at night. This cooling blanket made a noticeable difference almost immediately.
What impressed me most is that the cooling effect doesn’t just disappear after a few minutes. It stays comfortably cool and lightweight through the night without feeling damp or overly thin. Since using it, I’ve actually been tracking improvements in my sleep using my WHOOP device, and over the past 20 days I’ve noticed my deep sleep readings improving consistently.
The blanket also feels well made, soft, and lightweight without feeling cheap. For the quality and performance, I think the price is very fair, especially compared to other “cooling” bedding products that overpromise and underdeliver.
If you struggle with hot sleeping, night sweats, or menopause-related heat issues, I would absolutely recommend giving this a try. It genuinely improved my sleep quality.

Great blanket for keeping cool, but doesn't magically defy physics.
Size: King（103“*90”）, Color: Luxury Grey
This blanket is pretty awesome, and functions exactly as stated; however you might get the wrong impression from the image of the blanket in a the snowy mountains glowing blue as if its actively cooling. The blanket has two sides, the "cold" and "normal" side -- the cold side is the one that has the Q-max 0.45 effect, it actually feels cool to the touch. That being said, covering yourself with this blanket feels pretty similar to using a down blanket with a silk (or some cooler) fabric. It feels quite cool initially but eventually your body puts out enough heat and it "runs out" of cooling.
Although this blanket doesn't magically actively generate cooling, its quite effective because it operates fundamentally differently from most blankets. Most blankets are engineered to keep you warm by trapping heat in; this blanket is explicitly designed to draw heat away from your body. As such, it is extremely effective if you use a fan or run the AC, because your body heat is drawn away from the top surface and the inner surface can "grab" and remove more heat. As you probably know, air is a great insulator so this blanket has to be making contact with your body to achieve the cooling effect. If you are familiar with the way "Under Armor" works, I believe this blanket uses a similar principle to keep you cool.
This blanket is quite light weight and comfortable, with a very silky (polyester) feeling outer surface. I have not owned this for a year yet, but I'm quite confident that this blanket would be suitable for winter (in Southern California); except if you live in a snowy region.
5/5 for a somewhat high tech blanket that keeps you cool; its the best in cooling you can get without resorting to "active" cooled blankets such as ones with water circulation.

Fascinating product.
Size: Twin（90“ * 67”）, Color: Luxury Grey
It is a nightly struggle. My wife is a hot sleeper. I am not. It’s resulted in more than one argument. One of us is usually left shivering or sweating. So when Amazon offered to send me this cooling blanket, I thought I would give it a try. I’m really glad that I did.
This item arrived well packaged and in good condition. It is lightweight and made of a polyester type material. The stitching is strong. The first test was the washing machine. We washed it with cold water on the gentle cycle. We then line dried it. It held up fine.
We have a king size bed, but I decided to get a twin sized blanket. I put a warm blanket on my side of the bed and the cooling blanket on her side of the bed. It worked brilliantly. I don’t know what the science is buying these blankets, but it really does lower your body temperature. The moment that you open the package and feel the blanket, you’ll realize that it has some sort of cooling gel inside of it or something that draws heat away from you.
Suffice it to say that our first night with this product was one of the best nights sleep that both of us had. If you have a problem like this, I would definitely recommend this blanket as a viable solution.
In terms of value, I understand that this is not cheap; however, ask yourself what the value is of a good nights sleep. Overall, I’m very pleased with the quality, design, and functionality of the cooling blanket. I would definitely recommend it.

Cooler than my thinner blankets
Size: Queen (90" * 90"）, Color: Luxury Grey
This is a really nice cooling blanket—silky, soft, and comfortable. I actually tried it on a cold day (classic flip flip Rocky Mountain weather where it swings from 90° to 30° overnight), and it was absolutely freezing, lol. On warmer days, I can clearly tell that it's cooler than even my thinner blankets. My husband tends to sleep hot, and this works great for him. I run cold; it can feel a bit too cool initially, but that fades after a few minutes and stays comfortable.
I also have two cats and was worried they’d snag it right away. We keep their nails trimmed, but they’re still cats. So far (about a week in), no snags or pulls—but I’ll update if that changes since that’s a big factor for me.
At almost $100, it’s definitely not cheap for a blanket. I think it makes the most sense if you’re a hot sleeper or deal with night sweats—then the cooling effect feels more worth it. If you tend to run cold, it might feel like overkill unless you specifically want something for summer. Overall good value for a nice quality cooling blanket.
