The 1.0 TOG Pyjama's are the ideal next stage once your little one grows out of their Layers (onesies). Designed to support toddlers who have started toilet training and self-dressing who need a simpler solution than our zip-up Layers. The 1.0 TOG rating makes the Pyjama's an extra-warm layer for the cooler months, and are thicker and warmer than regular pyjama material. A drop-hem at the back of the top helps keep backs warm and prevent riding-up. The style is slim fit to ensure comfort when wearing underneath a sleeping bag or sleep suit without adding bulk, or on their own as regular PJ's in a big bed with blankets.
