The SleepSack Swaddle replaces loose blankets for safer sleep. It's the first and only wearable blanket endorsed by the SIDS Alliance and reduces the risk of rebreathing (the inhalation of carbon dioxide), which has been associated as a possible cause of sudden infant death syndrome. The Micro-Fleece SleepSack Swaddle is made of super-soft 100% flame-retardant polyester fleece and is great for the colder climates, but it offers superior breathability, making it perfect for year round use. Fits newborns 19" to 23" and 10 lbs. to 18 lbs.    The SleepSack Swaddle hugs your baby to prevent the startle reflex - allowing your little one to sleep more soundly. The 2-in-1 system allows you to swaddle from birth, but also allows you to move the swaddle feature down for arms out. The swaddle feature can be removed once baby is done swaddling and the wearable blanket can be used alone. The generous sack design allows room for kicking, but can't be kicked off so baby stays warm all night. The inverted zipper makes diaper changes easy, but won't pinch baby's skin. The SleepSack Swaddle features an embroidered "Back to Sleep" message to remind caregivers to place baby on his or her back. It also slips on easily over a regular sleeper or diaper and is machine washable and dryable with like colors.      Features:  Made of 100% flame-retardant polyester fleece  Fits newborns 19" to 23" and 10 lbs. to 18 lbs.  Reduces risk of rebreathing  2-in-1 system for swaddle or wearable blanket  Generous sack design allows room for kicking, but can't be kicked off  Inverted zipper for easy diaper changes  Embroidered message on chest  Slips on easily over a regular sleeper or diaper  Machine washable and dryable with like colors  .
