The breathable cover features a soft organic cotton surface and a 3-dimensional polyester lattice structure that allows air to flow through the fabric and under the baby for 360° air circulation. Since air is able to pass freely through the cover’s 3D structure, babies can breathe right through it! Breathable mattresses may also improve comfort. Babies tend to cry more when they're uncomfortable and airflow under the baby allows heat to dissipate more efficiently, helping regulate temperature for less sweaty backs.
