High-quality performance wear

The right thermal underwear or functional underwear makes all the difference. Our longsleeves, tank tops, boxer pants and undershirts are available in two high-performance versions: Merino SoftTec® combines natural merino wool with innovative high-tech yarns for optimal insulation, while Cool SoftTec is a super-light, year-round functional underwear that provides a pleasant cooling effect. Both options are temperature-regulating, breathable and exceptionally soft against the skin. Reliable clothing for cold conditions and sweat-inducing activities such as sports, outdoor adventures or everyday wear.

Breathable & comfortable

Lenz performance wear stands for top performance in terms of breathability and moisture transport. Whether you're jogging, skiing or doing other outdoor activities, the light and thin material prevents pressure points and ensures a comfortable fit, which also keeps you warm. Meanwhile, thanks to the quick-drying properties, your skin stays pleasantly dry even during sweaty adventures.
