Our sleepsack (up to 24 months), sleep vests and free-feet sleepsack are perfect (up to 5 years) for from babies up to preschool children. We are confident to say that unlike many other that sandwich and sew ready-made fabrics and materials together, our products literally start off as a thread - meaning we design and weave the thread to make our special fabric prior to creating a unbelievably soft and comfortable sleepwear for little ones for the quality of their sleep.
