Lässig Unisex Cream Smiley Sleep Sack, 7-12M

Scattered smiley faces in charcoal, sand and pale blue across soft cream muslin — a cheerful, gender-neutral sleep sack from German family brand Lässig. The multi-layer GOTS organic cotton gauze is light and breathable, and the pear-shaped cut leaves plenty of room for kicking. A long continuous zip with a chin guard makes night-time changes straightforward without waking a settled baby.
