What are Sleep Huggers sleep sacks made of?
All Sleep Huggers are made of 100% cotton fabric. We love using cotton because it is gentle on babys skin and allows it to breathe. Cotton also keeps your baby from becoming hot and sweaty, which can happen when using a sleep sack made of fleece. Sleep Huggers rated at 2.0 Tog and higher contain a naturally fire-retardant, naturally hypo-allergenic polyester filler to help keep baby warm.
