Why does my dock zipper have ripples?

Because of the curve at the top of the dock there is always a slight ripple in the zipper. However, if your ripple is more pronounced, it may be due to the distribution of the filling of the tube after washing.  In this case, shaking and fluffing the tube should even out the distribution of the filling.  If you have any other questions or concerns you can contact us at hello@eu.dockatot.com.
