Merino wool is the best material for baby sleepwear because it is naturally moisture wicking, which means that it absorbs perspiration from the skin and releases it into the air. Because of this, your little one will never feel clammy or uncomfortable, leading to a more peaceful night’s sleep for you and baby. Merino wool is also temperature regulating which is especially important for children under six months old who are unable to regulate their own temperature. This is why our sleeping bags don’t need a tog rating, because they can be used all year round to keep your baby cool in the summer and warm in the winter. Merino wool is proven to improve sleep routines and is also hypoallergenic and fire resistant.
