We cannot guarantee that YouZee fits in these types of masks/goggles, but we know that some use them for this purpose. However, it must be an open mask, as in the pictures below. All images have been sent to us by our customers. The first three images show a mask made by Cressi. The model is Z1 (the pink mask is their smaller version of the same mask). The next two pictures we don't know the manufacturer.

And below these are some pictures of masks where YouZee Clip-In has been tested but does not fit.
