The Baby Sleep Set

Our infant sleep sets and soft baby pajamas are made from our signature SollyLuxe™ fabric—a premium blend of TENCEL™ Modal and a hint of spandex. This ultra-soft, breathable fabric is designed to be gentle on baby’s skin while providing just the right amount of stretch for easy movement, making it ideal for both sleep and play.
Yes! Solly Baby’s baby sleepwear is crafted with sensitive skin in mind. Our SollyLuxe™ fabric is OEKO-TEX® certified, hypoallergenic, and free from harsh dyes and chemicals. These soft baby pajamas are a safe, soothing option for babies with eczema or other skin sensitivities
Yes, our infant sleep sets run true to size with a snug, stretchy fit that allows room for movement. If your baby is between sizes or you prefer a slightly looser fit, we recommend sizing up for longer wear and added comfort.
Absolutely. Our baby sleep sets are thoughtfully designed for both day and night wear. Made from breathable, moisture-wicking TENCEL™ Modal, these soft baby pajamas help regulate body temperature to keep baby comfortable all night long. Whether for naps or bedtime, they’re a cozy and safe choice for overnight baby sleepwear.
We recommend machine washing cold on a gentle cycle and tumble drying low. This helps maintain the softness, stretch, and shape of the fabric through repeated washes.
