The Kilpi REGIN-JB boys' fleece sweater is made of OPTI-HEAT material, which ensures thermal comfort even at the lowest temperatures. It helps to maintain one's own body heat and protects against the penetration of cold from the outside. A full-zip sweater with two pockets and a high collar will serve perfectly as a middle or outer layer for light hiking, leisure activities or just for a walk in the city. The shoulders are reinforced with a fabric that is more resistant to abrasion. We have a choice of Kilpi REGIN-JB in several colors. Material composition: 100% polyester
