Base layers are the foundation of layered clothing and determine how a child feels in the cold outdoors. They wick away sweat, keep the body dry and regulate temperature, whether it’s skiing, cross-country skiing or a winter hike. Without a good base layer, even the best jacket won’t help.

When choosing, pay attention to the material – synthetic for quick moisture wicking or merino wool for natural temperature regulation and odor resistance – and a snug fit that works well under other layers. In the subcategories you’ll find functional t-shirts, functional hoodies, functional pants and functional underwear from top brands. Choose the right layer and order with 24-hour delivery.
