Base layer for kids, perfect for sport and busy play. Super soft and elastic, very light material. Contains recycled materials.
Reima's base layer set is designed for sports and play. The material is light and soft and is ideal from the early autumn onwards, as it wicks moisture to the outer layers, giving a fresh feeling even when active in play. Reima tip: wear this layer under your football shorts and t-shirt while practicing outdoors.
Product information
Wash with similar colours, inside out. Do not use detergents with bleaching agents. Do not use fabric softener. Dry in room temperature.
