This Bj枚rn Borg Ace Women's Woven Tennis Track Pants are part of the Ace Woven training suit and can be combined with the matching jacket. These are the pants in the Night Sky color scheme.

At the bottom of the pant legs, there are hidden press-button closures that allow you to easily open and close the slits, making it easy to put on and take off the pants.
