who needs to iron anymore when knit light cotton shirts and creaseproof polycotton pants are the norm.
i'm not a fan of synthetics though. but i still probably wouldn't iron even if my combat pants were plain organic untreated no synthetics hemp or cotton anyway. and you never needed to iron wool, wool is teh other fabric i like. also, nobody had irons much before about 400 years ago, because nobody had cotton, because cotton basically wasn't existing. most people in europe were wearing wool knit fabrics and nobody ironed their flax/hemp based work clothes anyway.
ironing is a historical anomaly, a bit like the liberal democratic state that rose at the same time.
