Why We're Different
Slumber Cloud loungewear utilizes Outlast® technology for a unmatched approach to temperature regulation. Originally designed for NASA spacesuits, Outlast® technology is proactive, not reactive. As your body temperature increases during the day or activity, Outlast® technology stores that heat away from your skin to keep you cool, and then releases it back if you cool down...keeping you feeling “just right”.
Outlast® Matrix Infusion Coating is an advanced formulation of Outlast® Thermocules™ that's finely printed onto our loungewear fabrics. Outlast® MIC is ideal for loungewear products as it stays durable through multiple washes, has no impact of the fabric hand feel, and does not affect drape of the fabric.
Outlast® technology takes comfort to the next level by proactively alleviating spikes in skin temperature throughout the day. With Outlast® technology you will feel just right, no matter what the activity or season.
Laboratory tests show apparel treated with Outlast® technology helps reduce sweat by 30+%, compared to similar shirts made of modacrylic fiber. This is proactive reduction, not moisture wicking, and that results in greater comfort.
