3/4 undersuit with wide round neck, easy-sliding flat zip positioned diagonally from the neck to the lower abdomen and loops for the thumbs. Thin &thermoregulating: its particular 3d structure allows the fabric to self-aerate not only in a perpendicular but also lateral direction and to guarantee freshness and dry skin in all weather conditions
Technical characteristics of the fabric:
1) in contact with the skin there is the hydrophobic fiber in light polypropylene and thermoregulator which guarantees maximum breathability by conveying sweat to the outside
2) the outer layer is composed of the hydrophilic yarn in polyamide and polyester which absorbs sweat from the inside and spreads it along the entire external surface of the garment. A pump effect is generated between two layers that moves sweat from the skin outwards, in the hydrophilic layer, in contact with the air. Since the surface of the fabric is larger than the area of ​​skin affected by sweating, the sweat evaporation rate is significantly higher. Furthermore, sweat is impossible to return to skin contact, blocked by the hydrophobic layer
3) the third layer is composed of the elastomer that runs along the entire structure of the garment inside the hydrophobic layer. The structure of the elastic thread is tenacious and allows the retention of its expansion and contraction memory even after numerous washes.

The circular textile machines of RIDAY are of the latest generation and are able to create three-dimensional knit stitches: the extraordinary conformation of the fabric thus obtained allows ventilation of the garment not only in a perpendicular but also lateral direction, which optimizes ventilation and consequently the transpiration. In any climatic situation, intense cold or muggy heat, always dry skin will perform at its best giving you comfort and pleasant sensations.
