The Cocoon swaddle sleep sacks are designed to be simple to use and secure for babies. Rated 0.2 TOG, they provide the right warmth in rooms at 22–26°C / 72–79°F without the need for extra blankets. Parents can adjust layering according to the included clothing guide and free room thermometer. This zip-up design helps reduce the startle reflex while allowing natural movements that support healthy growth. Made from GOTS-certified organic cotton with a touch of elastane, the swaddle is soft, breathable, non-toxic, and stretchy. It expands with the baby’s breathing and allows hands in a self-soothing position. The bell-shaped design, approved by the International Hip Dysplasia Institute, is hip-healthy. Convenient snaps allow an easy transition from arms-in to arms-out swaddling. A two-way zipper makes nighttime diaper changes quick and simple.
