The lightest undershirt we've ever made, designed for ultra strenuous sports activities with heavy perspiration.

• Weighing just 80 grams, it boasts the highest concentration of transpiration technologies. Holes of different diameter positioned in specific areas of the shirt, three-dimensional micro-ribbing and the combined use of polypropylene generate an extraordinary flow of air on the skin. Excess body heat is dissipated immediately, without any negative impact on athletic performance.

Technologies:

• HYPERMOTION: Absolute freedom. Wearable. One shirt, one seam, no restrictions. The shoulder area is made of a single piece of fabric, with no vertical seams. More freedom of movement, greater support for muscles and for body posture.
• Flowtunnels: Future of ventilation. With the innovative Flowtunnels technology, different diameter holes are mathematically distributed in relation to areas of high body heat production. The perforation is designed to lighten the fabric without altering its characteristics of resistance and elasticity. The effect is twofold: the moisture produced during physical exertion escapes, while a system of three-dimensional structures allows the air to circulate freely between the skin and the fabric, exerting a cooling and at the same time insulation effect.
• NATEX: 100 % bio-based. 100 % functional. With the special NATEX yarn, UYN lets nature work for your wellbeing. NATEX is especially light and reduces the weight by 25 percent. NATEX garments dry up to 50 percent faster than comparable nylon clothing. The 100 %-natural organic fiber is more elastic and the bacteriostatic effect minimizes odors.
