Since 2015, we setup a factory to make dropstitch OEM products like SUPs , Air mattess and Floating Decks. During these years we have trained a group of professional designers and experienced workers especially for double air chamber tech. The whole process from material manufactuering, material cutiing, silk printing , bag sewing and testing are all finished by ourself. So quality is 100% under control. And we can also help a lot customers to upgarde their products with latest technology and new material.
