Nui BODY are our infant essentials in superfine 170gsm organic merino. The 170gsm weight is light, strong, fully machine washable and will maintain its color and shape for years. Soft and sleek it has the appearance of fine cotton – with all the attributes of intelligent merino. Perfect next to a babies skin, this organic merino breathes, regulates temperature, wicks away moisture, is naturally fire resistant with build-in elasticity to move every which way a baby does. Unlike cotton or synthetics, when merino does get wet it stays warm. Nui BODY fits ages newborn to 24 months.
