Cotton seersucker trousers. Most of the time seersucker is small and textured, this is much wider and smoother. Critically: it's breathable and packs like everyone's favorite avant garde polyester (but again: cotton). Pull it out of a suitcase and it's like new.
Naturally resists wrinkling
Elastic waist + drawstring
On-seam pockets, big patch pockets at side, back pocket
