Beat the Heat in High-Performance Kosto Workwear

When the heat hits, wearing the right workwear is essential to staying efficient and safe. This summer, Kosto delivers a range of high-performance apparel designed for tough jobsite conditions. Featuring technical fabrics like Ripstop and 37.5® technology, your crew will stay cool and dry without compromising on durability or visibility.

Do you know the 37.5® technology?

Thanks to the integration of 37.5® technology, the innovative fabric is composed of fibres with natural active particles, capable of effectively regulating body heat and staying cool and dry during intense work and in hot climates, by wicking moisture away from the body.

37.5 technology uses millions of particles to capture and release water vapor, creating a personal microclimate of relative humidity and body temperature. It's built directly into the fibres to last the life of the product, never disappearing in the wash.

These innovative new t-shirts from Kosto offer a unique and ideal combination of safety, comfort and performance, and will be perfect for workers who want to combine protection and well-being on a daily basis.

Browse our selection of summer-ready high-visibility workwear and be prepared for the season ahead.
