It’s so important to keep your little ones warm throughout the year here in New Zealand. We have a wide range of thermals which are perfect for babies and for younger children. Our baby thermals are perfect for keeping your newborns snuggly and warm both inside and out and about. Wrapped up warm against the cold, they’ll be snug as a bug in a rug in our baby thermals.

Our kids’ thermal range also includes a range of children’s merino clothing which is lightweight and super warm. Merino is also a great material all year round thanks to its moisture wicking properties – perfect for kids any time of the year.
