1. Best Overall: SIJO CLIMA All-Season Comforter
Made of a Tencel and nylon blend, the CLIMA comforter works to keep your body at a comfortable and optimal temperature.
For example, when you're hot, the comforter absorbs the heat and releases it back to your body whenever you feel cold. It's able to do this because of the brand's CLIMA technology, which uses phase-change material to maintain the body's temperature.
This blanket is also Oeko-Tex 100 certified, which means it's free of harsh chemicals and dyes.
Whenever this comforter needs a clean, simply throw it in the washing machine on a cold cycle.

What to Look for in a Cooling Comforter
1. Cooling Technology
Most cooling comforters use signature technology — which consists of a blend of fibers and materials, such as polyester, Tencel, and cotton — to regulate body temperature.
So how does cooling technology work exactly? Well, when your skin's temperature increases, the material absorbs the excess heat to prevent you from overheating. When you get cold, the material restores heat back to your body.
2. Materials and Breathability
When you're on the hunt for a cooling comforter, it's best to "avoid too bulky or heavy comforters," which can trap heat, Dr. Vyas says.
Cooling comforters are usually made of breathable materials and fibers, such as polyester, Tencel and cotton. These materials are known for absorbing heat, which can help decrease your overall body temperature.
Additionally, if you have sensitive skin or are prone to skin breakouts, Dr. Vyas says to "look for fills without too many synthetic ingredients." (Think: polyester.)
If a comforter is synthetic and chemical-free, it will be labeled Oeko-Tex 100 certified.
The best cooling comforters are usually lightweight, which varies by brand. If your comforter is weighted, it will weigh between 10 and 25 pounds. Follow the brand's instructions for choosing a blanket weight.
Cooling comforters come in myriad sizes, from twin to California king, so choose one that fits your bed's size. For example, if you have a queen bed, choose a queen-sized cooling comforter.
The majority of quality-made cooling comforters cost between $100 and $200. If cost is a concern, there are some affordable options under $100, including the COHOME King 2100 Series Cooling Comforter and the Luna Cooling Bamboo Weighted Blanket.
