The ergoPouch Sheeting Sleeping Bag for 3-12 Months Babies is a baby and toddler sleeping bag designed for arms-out sleepers (usually from around 3 months of age) who prefer more room in their pouch. The safe-sleep approved design is made with a 400 thread count organic cotton outer that feels smooth and luxurious on baby’s skin. The ergonomically-designed bag features a wide-fit and unique stretch jersey cotton inserts on the sides and shoulders to allow baby to move more freely and stay comfortable while they sleep. The 2.5 TOG Sheeting Sleeping Bag is perfect for keeping a child warm overnight in rooms 17-23 degree Celsius. The bell-shaped design is hip-friendly for growing hip joints and the two-way zipper gives easy access for quick overnight nappy changes. All ergoPouch fabrics are dyed with non-toxic water based dyes.
