Bamboo sleep sacks with a zipper built for midnight diaper changes.
Gunamuna is a baby sleepwear and daywear brand focused on making sleep and diaper changes easier. Its sleep sacks and swaddles are built from bamboo rayon fabric with a breathable down-alternative fill.
The brand's patented WONDERZiP zipper lets parents open a sleep sack for a diaper change without fully unzipping, and its DIAPER-ZiP system carries the same idea into daywear. The lineup extends to pajamas, sweatsuits, rompers, bedding and loveys.
Gunamuna says its fabric is OEKO-TEX Standard 100 certified, meaning it is tested to be free from harmful chemicals and irritants, and offers sleep sacks in 1.0 and 2.5 TOG warmth ratings.
