Cooling shirts for hot weather – nothing new, right? However, temperature regulating shirts with the Outlast® thermo-technology function differently than most body cooling t-shirts do. And here is why:

• Most clothing designed to keep the wearer cool consists of fabric which enables passive thermal management. This means that the fabric does not react to temperature changes in its environment. Instead, it has a certain structure which allows the body to cool down naturally more efficiently. Heat peaks, therefore, cannot be prevented, but they may not last as long as they would if another fabric had been used.
• If temperature regulating fabric with Outlast® thermo-technology is used, the clothing provides active thermal management. The material adapts to temperature changes in the environment and acts proactively and anticipatory. Due to that, heat peaks can be partially prevented, and a significant reduction of sweat production is accomplished.

In the case of temperature regulating shirts with our Outlast® thermo-technology, no additional energy source is needed to make them work. This also means that they are highly reliable, as they will keep functioning.

The heart of this technology, which can be used for making temperature regulating shirts, is the microencapsulated wax. This wax is usually based on rapeseed oil and is responsible for the cooling effect. In the case of a temperature control shirt, the user's body serves as a heat source. Because of the heat coming from the body, the wax melts. According to a physical law, the temperature cannot further increase during this change from a solid to a liquid state, and as a result, the body does not heat up any further. The thermal energy does not affect the microclimate, but instead is used to melt the wax. This significantly reduces and even partly prevents the user's heat peaks and keeps them at a comfortable temperature.

We decided to take this technology even further – and the results are Xelerate and fresh2SKIN®. In Xelerate products, the natural wax is specially equipped with heat-spreaders. Between the body of the user and the t-shirt, a heat transfer happens. Usually, the material reacts in the spots in which the body and the shirt are in contact. But the heat-spreaders divert the heat to the surrounding areas as well. This increases the thermal conductivity by up to 30% and reduces sweating even more efficiently. fresh2SKIN®, on the other hand, focuses on increasing the cooling effect by using natural menthol. Temperature regulating shirts with this technology, therefore, have an even stronger cooling effect because the cold receptors in the skin respond to the menthol and can increase the comfort of your customers even more.

Temperature regulating shirts and other cooling technology clothing offer many advantages which increase the value of your products for your customers:

• The biggest and most obvious advantage of temperature controlled clothing is that they significantly reduce heat peaks – and also freezing. The wax either melts or solidifies and thereby provides a stable microclimate.
• Furthermore, sweat production can be reduced by up to 48%. This highly increases the comfort of the person wearing it.
• As a result of the significant reduction of sweating, body odor can be reduced as well. This can make the user of the product feel more comfortable and confident in their everyday life.
• Because less sweat is being produced, the temperature regulating shirts do not need to be washed as often as regular shirts. This saves water and washing powder.
• And most importantly: Every person can benefit from the advantages of temperature regulating shirts. Whether it is hot flashes during menopause that are making life hard or if the person is an athlete who wants to feel more comfortable during their workouts – the temperature regulating shirts with Outlast® thermo-technology will leave them feeling just right!
