OutlastTechnologies, Inc., a privately held U.S. corporation, is the worldwide leader in phase change materials and applications. Outlast^® technology is the heat management technology originally developed for NASA that enables any textile to absorb, store and release heat. Outlast^® technology pro-actively responds to changes in skin temperature to manage heat and reduce moisture for everyday comfort.

For over 20 years, Outlast has been committed to the development of new fibers, fabrics and coatings incorporating phase change materials, expanding the use of Outlast^® technology across more than 200 brands and a multitude of products in apparel, footwear, bedding, packaging and labels, and accessories.

Not too hot, not too cold, just right

Outlast^® materials absorb excess body heat when too much is created and release it again to the body when needed. Welcomed “side effect”: Sweating is reduced dramatically temperature is balanced actively and dynamically. Outlast^® products reduce overheating and shivering, the warmth is distributed regularly. All in all comfort is increased significantly.Not too hot, not too cold – just right. That is the easy way it works. Pioneer and market leader is the US company Outlast Technologies, Inc., headquartered in Boulder/Colorado. The Outlast^® PCM technology was originally developed for NASA to protect astronauts against the extreme temperature fluctuations in space.

But what are PCMs? The principle is simply demonstrated. Looking at phase change materials (PCM) two well-known technologies are successfully combined: On the one hand is the microencapsulation, as known from the chewing-gum inside which microcapsules are embedded. While chewing the shell is destroyed, and the taste is released. Another example: perfume probes in magazines. The microcapsules being destroyed while rubbing on the paper, as the smell is released. The difference in Outlast^® materials: Microcapsules are also used, but the shell is stable and doesn’t get ruined. The capsules are very tiny: Around 1,000 fit on the head of a pin(ca. 3 million per cm²). Inside the patented microcapsules, called Outlast^® Thermocules™, substances similar to paraffin are stored, which are capable of phase change. This simple physical principle is well-known to everyone, example H₂O: Water becomes ice or vapour when energy is added or taken away. PCM technology takes advantage of exactly this same law of physics. The advantages of Outlast^® products on a glance:

·                                 Absorbs excess body heat

·                                 Manages moisture

·                                 Reduces overheating

·                                 Reduces chilling

·                                 Reduces perspiration

·                                 Continuously adapts to thermal changes

Everybody’s sensitivity to temperature changes is different, which means everyone sweats or becomes chilled at different rates; quickly or slowly. But the temperature corridor in which we feel comfortable is relatively narrow: when the body core temperature of 37°C fluctuates only 2°C upwards or downwards we are subject to fever or hypothermia. Here Outlast^® products help. They reduce temperature swings and influence the comfort zone efficiently. The microclimate is well balanced, one sweats less and is less chilled. You feel not too hot, not too cold, but just right^®.
