Why sports underwear also makes sense in summer _{Jun 2023}

At high temperatures or during strenuous exertion, our body uses an ingenious system to ensure that it does not overheat. It produces sweat (up to 1.5 litres per hour). The sweat extracts heat from the body through evaporation, which has a cooling effect and thus regulates the body temperature. However, the right functional underwear is crucial for this in summer:

• Sweat can only have a cooling effect if it actually evaporates. If evaporation is hindered by the wrong clothing, cooling no longer works sufficiently. Performance is correspondingly limited. The evaporation of sweat must be supported by the clothing. To accelerate evaporation, the fibres in the fabric distribute the moisture over a large area.
• Excess sweat must be transported away from the skin and released to the outside. Functional textiles must draw perspiration away from the body so that the body can continue to sweat and thus cool down.

transtex® is made out of polypropylene. Polypropylene is the lightest synthetic fibre, it even floats on water and absorbs almost 0% moisture itself. Therefore …

• … transtex® transports perspiration better and faster than any other material.
• … the skin stays pleasantly dry, which feels good and prevents colds and muscle tension.
• … no odours develop. transtex® does not require any chemical finish or controversial silver ions. This is particularly important for underwear that is worn directly on the skin.

Functional underwear also makes sense in summer. It keeps the body dry and regulates the body temperature like an intelligent air conditioner. Thanks to the different transtex® fabrics, Löffler offers functional underwear for every sweat-inducing activity, whether cycling, speedhiking or hiking.
