You can take 2 gloves and flip one inside out and attach it to the other. How ever you want to explain it... The zip portion, whether it is on the suit, seal, or glove is all the same piece. Dui just flips them depending on their orientation for gluing. So all the zip products are the same zip.
(this is only for the generation 2 wrist zip systems. I do not know if it will work with the generation one wrist zip system. You would have to experiment for yourself on that.) To know the difference between the two generations, go to dui website. They have a few photos to show the difference between the two styles of wrist zips.
