How the Outlast® thermo-technology works

How natural wax makes life more comfortable

Like a sponge absorbs water, Outlast® thermo-materials can capture and store heat. But how exactly does that work?

How the Outlast® thermo-technology works

Via a heat source, usually the user’s body, heat is transferred to the Outlast® thermo-material. This features applied or incorporated microencapsulated wax (usually based on rapeseed oil), which is liquefied under the influence of heat.

The wax is safely enclosed in microcapsules. According to a physical law, the temperature does not increase any further during the change of physical state from solid to liquid. Figuratively speaking,  the thermal energy can be used to overcome the physical state of the wax. And this is where the Outlast® effect becomes palpable: The body heat no longer heats up the microclimate, but rather makes the natural wax melt. The Outlast® thermo-material thus acts as a heat buffer, significantly reducing the user’s heat peaks. This leads to considerably improved comfort and prevents sweat formation by up to 48%*.

A constantly balanced microclimate

The great thing about this technology is that it works in both directions – cooling or heating depending on the situation. As the body cools, crystallization occurs in the Outlast® thermo-material – once again a change of physical state, but one that releases heat. 

This cycle of solidifying and liquefying the natural wax within the microcapsules does not wear off, but instead functions continuously and repeatedly. Outlast thus permanently achieves a constantly comfortable temperature with its textiles, despite continuously changing temperatures and external influences around us over the course of a day or during the night.

The Outlast® cycle

Xelerate – a new stage in evolution

Xelerate – a new stage in evolution

The company’s innovative spirit continues unabated. The Heidenheim development team thus combines the Outlast® thermo-material with an innovative technology that can dissipate heat extremely quickly. Xelerate was created from this interaction. Xelerate makes it possible to distribute the absorbed heat extensively via a mesh structure to once again significantly increase the heat absorption capacity.
