We recommend taking our Sleep Bag Quiz here: Sleep Bag Quiz
Below is our recommended sizing chart to to assist with determining which size sleep bag is the best fit for your child. We do not recommend sizing up. You want to be certain that the sleep bag is well-fitted around your child's upper body. The goal of a good fit in a baby sleeping bag lies more in the chest and neckline than in the length. As the sleep bag size increases, not only the length increases, but the chest width, neck, and arm openings, too.
We're here to help you find the best fit for your little one! Please use our recommended sleep bag sizing guidelines below to find the correct size based on your child's height & weight.
