What is the reason mesh is lined on the inside when the hem zipper of the pants is opened?
When the hem zipper is opened, bare skin is not immediately exposed and a mesh fabric connects it, making one wonder what its specific use is.
It is a structure that widens the hem width when the zipper is opened while helping air circulate through the gap at the same time.
When closed, it is neat; when opened, room and air open up together. ostrya fitted a mesh panel-integrated zipper to the hem of the Active Pants so that ventilation and width adjustment occur together when the zipper is opened[1]. Unlike zippers where only a slit opens up, it is a structure where a mesh fabric connects the opened gap.
Mesh is a fabric woven so that air can pass through fine holes. When wearing high-ankle shoes, pulling up the hem zipper naturally widens the pant leg width[2], and leg heat that builds up while walking also escapes through the gap[3]. Because the gap is not completely empty, it also helps prevent grass blades or small foreign substances from entering straight into the pants during outdoor activities.

Specifically how many cm the hem circumference widens when the zipper is opened all the way has not yet been confirmed.
