It’s designed to make sleep feel familiar and comforting especially for babies transitioning out of the swaddle.

Could it cause overheating?Each Zen Sack is available in a range of TOG levels for different seasons and room temperatures, so you can pick the right one for your baby’s needs to maintain optimal body temperature.
