front-to-back zipper pants

A style of pants, particularly women's denim pants, with a zipper that runs the full length of the pants from the front going down around the crotch and up the back.

They may visually be similar to back zipper jeans where the zipper run from the top of the back of the pants all the way down to the crotch, though the slider on front-to-back jeans will be in the front when zipped while the slider on back zipper jeans when zipped will be on the back.
