Slate is a medium blue-grey with real depth — richer and more grounding than a pale neutral, it brings a quiet sense of structure to the nursery without leaning cold. This sturdy favorite is made from silky-soft rayon made from bamboo, with a breathable, temperature-regulating feel that makes the 1.0 TOG the right weight all year long. Best for rooms between 69–73°F, layer over a short-sleeved onesie on warmer nights, or add a footie pajama when temperatures dip closer to 69°F. A comfortable pick for little ones with delicate skin.
