Abstract: A fly for a flexible panel or closure, such as for a garment such as pants. The fly may have a generally L-shaped opening and an overlying cover panel which significantly overlaps the opening it covers. The overlying cover panel may have a pull tab. Closure may be magnetically enhanced. Pants having the fly may include front and/or rear discharge suppressing panels. Constituent material of garments may comprise nylon and polyester generally, with cotton portions and a spandex waistband, and may be sufficiently rigid in places to avoid bunching and to automatically align the overlying cover panel with the opening when released from manual grasp. Short pants such as underwear may be long enough to oppose spontaneously riding up in the course of use.
