You can wear the sleeper when you go to bed and rest assured that it will protrude from your futon. It prevents the cooling from sleeping in the summer and keeps warm air from escaping in the winter. By stacking 6 layers of gauze with different weaves, it contains fluffy air, and quickly absorbs sweat when its cold or when its hot, and it dries quickly. The gauze material has excellent breathability and quick drying properties, so it can be used all year round. Snap buttons on the right shoulders and sides allow for easy diaper changing. The fabric has been woven with 6 color threads to create a small cross pattern. The embroidered walnut button is the main point.
