Well then if you really want to know, I can tell you that I think that all zippered products for men should be operated from the right. That is the way they are accustomed to using the zipper.

While I can quickly start the zipper and zip up my pfd without even looking, if it were backwards it would cause a short stumble of my attention.

Women can use zippers easily from either side because they are used to using both. So a unisex zipper should be of the male gender and be operable with the right hand.
