Used safely in Europe for over 25 years, baby sleeping bags ensure that your child is always covered and warm, regardless of how actively they may sleep. Baby sleeping bags are the safer, more comfortable alternative to traditional loose baby bedding. Designed as a wearable blanket, a baby sleeping bag keeps your baby comfortable and warm all night long, so you'll sleep better too! Is your baby sweaty in their sleeping bag? Synthetic fibers like fleece and polyester absorb moisture in very small amounts and hence are the least desirable fabrics touching your babies skin. With our bags, only soft jersey 100% cotton touches your baby's skin, allowing for as comfortable sleeping experience as possible. If babies are comfortable, they tend to sleep longer. So enjoy that extra rest!
