The X-Cozy Jersey is a technical 3-season baselayer with seamless technology and a run-resistant structure, designed to offer superior biomechanical comfort and total freedom of movement. The textile composition of polypropylene, nylon, and elastomer combines high hydrophobic and thermal properties: polypropylene, in particular, ensures optimal sweat management and thermoregulation during intense sports activities. The garment's architecture integrates zones with differentiated ventilation with micro-holes on the chest and back to maximize breathability. A distinctive feature is the modular sleeve structure: thanks to the run-resistant technology, it is possible to cut the long sleeve to transform the garment into a short-sleeve version without the fabric fraying. The ergonomic and snug fit, completed by the front Acerbis logo and rear graphics, makes the jersey an ideal first layer for maintaining the body's microclimate.
