Gently used Nui Organics footed Merino onesie with front zip in grey blue. Size 12-18 months and fits TTS or perhaps a tiny bit small. Perfect for layering in winter but not too hot—my son wore this when we were in the mountains under his bunting suit and it was just perfect. Has a tiny hole (about half the size of an eraser head) at the seam, but totally functional—see photo for details. Washed in free & clear detergent, never dried. This style is sold out or has been discontinued (sadly!). From Nui: Butter soft and baby pure, our soft and pure GOTS certified 100% merino keeps little ones warm from top to toe. Temperature regulating, breathable, fire resistant, calm and soothing. Machine washable and fast drying.
