From ergonomic studies to the interpretation of enhanced wearability. For Rosti’s long-sleeved underwear the density and elasticity of the fabric are used in a calibrated way. Special attention to the back of the vest with a special texture that makes the upper part of the back, from the shoulder blades up, feel more protected. Stretch side panels to favour correct movement of the upper body. A 3 cm hem for a perfect length. The fabric is 90% Polypropylene and 10% Elastane. Total black.
