Often when the thermometer reaches up to 40°, there is a fear of wearing a garment in contact with the skin that feels too hot. Precisely because it is hot and you sweat more, it is important to wear technical underwear that keeps the skin dry and quickly transports sweat outside. The fabric with BTX fiber in Polypropylene, used in this short-sleeve shirt, allows an immediate sweat breathability capacity, ensuring a body that is always dry and fresh even in very hot and humid climates. The Summerlight T-Shirt is among the lightest and most breathable short-sleeve underwear shirts. This innovative fabric is bi-elastic and offers a perfect anatomical fit. Maximum comfort and total freedom of movement are due to the absence of seams and its lightness. The Summerlight T-Shirt has a very tight fit: with only two sizes it is possible to fit from XXS to XXL. Designed for cyclists, it adapts to all outdoor sports.

For over 20 years at Biotex we have been producing technical underwear to improve sports performance.

We were the first Italian company to experiment with and use Polypropylene in our products, which ensures breathability, lightness, and constant body thermoregulation.

We are also partners of professional sports teams with whom we test the effectiveness of our technical clothing in the field to perfect it and make it high-performing for every type of sport.

The wide mesh bi-elastic T-Shirt keeps the body dry and thermoregulated, not only during physical effort but also during breaks or rest. The short-sleeve shirt, from the Powerflex line, is extremely light, comfortable, and breathable. The effect felt is that of a second skin and therefore one with your body. The elasticized mesh (both lengthwise and widthwise) with which the underwear shirt is made is seamless (on the sides), adapts to the body shape, and emphasizes the musculature.

Fit is the difference between the body and the worn garment and its adaptability to the wearer. For the first layer in contact with the skin, we suggest garments that fit the body for greater functionality.

POWERFLEX is the bi-elastic mesh with unique characteristics: the fabric is completely snag-proof, seamless, and highly resistant. Very light and breathable, it is suitable for outdoor sports activities in warmer seasons. Ideal not only as underwear but also as an outer garment for running and gym. In contact with the skin, the fiber is BTX yarn in Polypropylene. On the outside, Lycra and Nylon offer elasticity and design.

Each Biotex line is characterized by unique elements that distinguish it for thermal properties, fit, compression, and design, but all aim to improve body performance during aerobic activity.

Take care of Biotex garments and their use will be ensured for a long time. It is recommended to wash the garment before use to avoid possible color transfer to other garments. To maintain its characteristics unchanged, a gentle wash inside out at a maximum temperature of 40° and air drying are recommended. Make sure everything is closed: zippers, buttons, Velcro. It is recommended to avoid or reduce the use of fabric softeners (they inhibit breathability). Do not place on radiators or other direct heat sources and do not use an iron. Otherwise, we cannot guarantee the garment's effectiveness. Bright/fluo colors may fade.
