The Polaris by Erreà thermal shirt is part of the 3D Wear Performance line. This long-sleeved, round-neck undershirt is perfect for all sports thanks to its highly technical fabrics, which have been specially designed to offer support and protection in all conditions. The special knitted tubular fabric technology used to manufacture this garment reduces seams to a minimum, to offer the utmost comfort and fit. The fabric is highly breathable and has an athletic design with an ergonomic cut. Polaris is a short-sleeved thermal shirt, available in 9 different shades to suit your tastes. This round-neck model, used by boys and girls alike, is best suited to winter: thanks to the technology used to produce it, this garment allows perspiration to evaporate, keeping your skin cool and dry. It also protects against the cold, stabilizing your body temperature. To enhance the garment's breathability and ensure optimum ventilation, a large Erreà logo on openwork fabric has been added to the front and back.
