Mountain sports can be physically demanding and whether you’re walking uphill or skiing down, the exertion creates sweat. Our kids’ thermals and base layers range is designed to move this sweat away from your skin. This process is called wicking, and it is an essential part of any mountain clothing system. Synthetic base layers use capillary action to draw moisture through to the outer surface allowing evaporative cooling. Boys’ and girls’ Merino base layers use fine-grade wool (often sustainably farmed from sheep in New Zealand).

Children’s Merino base layers are particularly effective as thermal underwear in the cool or cold conditions found when skiing or mountaineering. It is especially important for children’s winter thermals to have performance and wicking properties, because sweat can be very uncomfortable when it cools during inactive phases. Therefore avoid cotton at all costs – it will hold sweat next to your child’s skin, feeling clammy while they’re hot and then cooling rapidly when they stop being active. Modern waterproofs and fleeces are highly breathable, but only if sweat is able to reach them.

A fully-functioning kids’ base layer provides the foundation for an effective clothing system so take your pick from our extensive range of performance boys’ and girls’ base layers from top brands like Smartwool and The North Face.
