Cocoon swaddles are offered in a lightweight 0.2 TOG (for warmer room conditions) and a warmer 2.5 TOG (for cooler rooms). The higher-TOG styles include a lower-rated chest panel to improve ventilation and help reduce overheating.
Cocoon swaddles use a zip enclosure—often a two-way zipper—so you can open from the bottom for quick diaper changes with minimal disruption to sleep.
On the warmer 2.5 TOG styles, the chest area is specifically rated at 1.0 TOG to improve ventilation and help reduce the risk of overheating while allowing full chest expansion.
Cocoon swaddles use fabric blends with some stretch combined with firmer construction to give a snug, supportive feel that helps reduce the startle reflex while still allowing the baby to move hands into a self-settling position inside the swaddle.
The 2.5 TOG swaddle is described for newborn sleep and can be used in three ways: as a zip-up arms-in swaddle (suitable from birth until rolling), paired with a separate cardi to create a hands-up position, or as an arms-out sleep sack. These configurations let the garment be used as the baby grows.
