Merino Thermal Base-layer Set - silver gray

 Amazingly soft, cozy, and versatile Thermal Base Layer Set is the ultimate choice for keeping your little ones snug and comfortable during chilly nights or as a cozy base layer in any weather adventure.

Our thermal set is made from the finest 100% NON-superwash merino wool fibers. It is ideal for maintaining a consistent and comfortable environment for children's well-being, ensuring they stay cozy without overheating. The thermal base set provides insulation by trapping body heat while allowing moisture to escape, keeping your child warm and dry during sleep, playtime, or adventures.

The Base Layers are incredibly soft, ensuring irritation-free comfort all day long. They are designed for a snug fit without restricting movement. They harmoniously blend with any of our sleep sacks.
