Unfortunately, the product was disappointing. For the price we would have expected a better quality: - The zipper is one of the cheap variety. He hooked up repeatedly on the substance or on the label and is running very hard. The hook arises now and then crosswise, so that the zipper is completely blockert. - The Kletttverschluss on the left shoulder "stuck" after a while no longer so that the baby's arms exposed. This means that our only 9-month-old daughter either twisted in a sleeping bag or completely can peel from the Schläfsack - an absolute no-go. - Positive is the filling of the sleeping bag and the thermal property related.
