When it comes to keeping your little adventurers warm and comfortable, Smartwool's kids' base layers are the perfect choice. Made from premium Merino wool, our kids' base layers offer the same outstanding benefits as our adult lines, making sure your children stay cozy, dry, and ready for anything. Whether they're building snow forts, skiing, or enjoying a family hike, our base layers provide the essential foundation for their outdoor activities.
Our kids' base layer tops are designed to deliver optimal warmth and comfort. They provide excellent insulation and moisture management, making them perfect for cold-weather adventures. The soft, breathable fabric keeps your child comfortable while preventing overheating. For active kids who need additional flexibility and ventilation, these tops offer innovative knit technology that adapts to their movements and activities.
Pair our base layer tops with our kids' base layer bottoms for complete coverage and comfort. Designed for warmth and durability, these bottoms provide an extra layer of insulation during chilly outdoor play. They feature targeted ventilation and enhanced flexibility, ensuring your child can move freely while staying warm and dry.

Q: Can kids' Merino wool base layers be worn alone or only as an underlayer?
A: While they are designed to be worn as a base layer, Merino wool tops and bottoms can also be worn alone in milder weather. They provide excellent comfort and temperature regulation in various conditions.
Q: How do I choose the right size for my child's base layers?
A: We recommend using our size chart to find the best fit for your child. Base layers should fit snugly but not restrict movement. If your child is between sizes, consider their growth and choose the size that allows for some room to grow.
Q: How long do Smartwool's kids' base layers typically last?
A: With proper care, our kids' base layers are designed to be durable and long-lasting. The high-quality Merino wool and reinforced construction ensure they can withstand frequent use and washing.
