The Helly Hansen Kids’ LIFA® Merino Midweight Base Layer Set includes a long-sleeve thermal top and matching bottoms, giving kids a warm, moisture-managing foundation for outdoor school, skiing, sledding, hiking, winter travel, and everyday outdoor play.\u003c\/p\u003e\n\u003cp\u003eHelly Hansen’s two-layer LIFA® Merino construction pairs moisture-moving LIFA® fibers next to the skin with breathable Merino wool on the outside. As kids run, climb, build snow forts, and explore, the inner layer helps move perspiration outward while the wool provides insulating warmth and helps regulate temperature. When the pace slows for snack time, the ride home, or a quiet moment outside, Merino wool continues to insulate when damp.\u003c\/p\u003e\n\u003cp\u003eMidweight warmth, flatlock seams, and a streamlined layering fit make this an easy foundation beneath fleece, snow gear, rainwear, and winter outerwear.

LIFA® fibers help manage moisture during high-energy play, while the Merino wool outer layer adds breathable insulation for cold conditions. Together, they create a practical first layer designed to help kids stay comfortable through the movement, pauses, and changing pace of a real day outside.\u003c\/p\u003e\n\u003cp\u003eThe close-to-body, midweight design also leaves room for the rest of a flexible winter layering system.
