New! Not Too Hot, Not Too Cold™ Outlast® Mattress Protector

Protect your investment with this easy care Outlast mattress protector. This fitted bed cover not only keeps your bed stain free but it also has an Outlast® Gold Rating to help manage temperature swings all night long.

Outlast® "Not Too Hot, Not Too Cold™" technology, originally developed for NASA, utilizes phase change materials (PCM) that absorb, store and release heat for optimal thermal comfort. Outlast® technology is comparable to ice in a drink; as it changes from solid to liquid, it absorbs heat and cools the drink, keeping that drink at the desired temperature for longer. Outlast phase change materials work in the same way, but are microencapsulated to be permanently enclosed and protected in a polymer shell. We call microencapsulated phase change materials Thermocules™.

This encapsulation process makes the Thermocules™ exceptionally durable for many applications. These Thermocules™ can be incorporated into fabrics and fibers and have the capacity to absorb, store and release excess heat. This gives any product containing Outlast technology the ability to continually regulate skin's microclimate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released.

Outlast® is not wicking technology, which manages moisture by reacting to your sweat and pulling it away from the skin. Outlast® will proactively manage heat while controlling the production of moisture before it begins.

This Outlast mattress protector proactively manages heat and moisture to give a better, more comfortable night's sleep. From menopausal women to thermally incompatible couples, this fitted bed cover is tested and proven to alleviate spikes in skin temperature that cause sleep disturbances.

Outlast Rating At-A-Glance
Outlast's comfort rating system will help you distinguish the right product for you. Product performance is based on the following levels: Gold, Silver and Bronze. A higher rating indicates a greater capacity for heat storage, resulting in more comfort.

Gold: appeals to people who experience night sweats such as women exhibiting symptoms associated with menopause.

Silver: suited for thermally incompatible couples

Bronze: sufficient for normal sleepers in search of a more comfortable night's sleep.

** Products carrying the silver comfort rating do not offer the same heat and moisture management capabilities as our gold level core bedding products. This is due to the fact that an Outlast fiber is used as opposed to a fabric coated with substantially more Outlast technology found in our gold level products. As a result these blankets should be sold as a supplement to our gold level core bedding products, not a replacement.
