What is heat-managing Outlast Technology?
From the Slumber Cloud website, the Outlast Technology in the Dry Line mattress protector is described as, “a unique material that can absorb, store and release excess heat. As an individual’s skin temperature increases, the technology will absorb that excess heat to help prevent overheating. The material will store the excess heat until the skin temperature begins to drop.”
The Dry Line Mattress Protector feels dense and durable with its 98% polyester, 2% lycra knit waterproof cover fabric. It drapes on the mattress nicely and is heavy enough to naturally hold its place so it’s not moving around on the bed.
The top of the Dry Line mattress protector is said to be waterproof, so I decided to put this to the test.
I poured 6 ounces of water directly on it and let it sit for more two hours. After pulling up the protector and swiping my hand under the soaking protector I felt no moisture or dampness. It passed the waterproof test for me with flying colors.
Keep in mind that the parts of the protector that cover the sides are not waterproof. If a spill/leak/accident happens on the top of the mattress protector – but close to the side or a corner – it could be absorbed by the side material and transferred onto the mattress.
The Dry Line mattress is said to be geared towards individuals who “experience mild sleep discomfort and temperature swings.”
I did my best to control the rest of my sleep environment when assessing the temperature controlling capabilities of this protector.
I set the same temperature at my house (73 Fahrenheit), wore the same pajamas (100% cotton long sleeve and long pants) and kept the same sheets on my bed (Brentwood Home Sonoma sheets).
I slept with the mattress protector directly under my sheets – no mattress pad – for three nights.
Each night the bed felt cool, even to the point that I was a little chilly. But soon my body temperature acclimated and it became quite comfortable.
But I also woke up each night in various stages of being overheated. The first night I was drenched in sweat (sorry for the overshare).
The second and third nights I was not as sweaty, but definitely warm.
Overall, I did not feel like the Outlast Technology process was working for me with this mattress. It may have absorbed all my body heat at the beginning of the night, but then it almost must have released it all at the same time – making me hot and uncomfortable.
Price and Value
This mattress protector ranges from $139.99 for a Twin to $189.99 for a Cal King. This is definitely on the pricier side for mattress protectors – but it does promise a lot.
I think if people have serious body temperature swings, want something waterproof and have a thicker mattress, this mattress protector could be a potentially good fit.
I found the actual mattress top to be comfortable and reduced noise – that “crinkling” sound that often accompanies mattress protectors. I felt like the weight of the product was a nice quality and the construction seemed well done.
For those looking for something to simply lay on top of a mattress to make it more comfortable – like a mattress pad – this would not be an especially good fit. This is designed to be more of a protector than a pad.
