Cotton chills kids when moist, but the warm Lani base layer set with Thermolite transfers moisture away from the skin. It keeps kids comfortable, no matter how many trees they climb, snowmen they build, or slopes they slide. Because the Lani kids' thermal set is the base we build our winter attire on, Reima offers it in a wide size range from toddlers to teens. Found best in its class by the Nordic Bast i Test jury in 2023: "A base layer set that keeps warm and is comfortable with flat seams".
