I only ever use non-iron shirts.
Cotton rich, mainly M&S although I picked up a lovely shirt (expensiveish – £65) from my local gents outfitters that’s non-iron too the other day. M&S do a “pricey” version non-iron that has a good feel. I odnt like double cuff heavy cotton shirts as a cyle in my work shirt and roll sleevs all day whilst I type – M&S are great for me, but its not going to win any prizes on Saville row, but then Im too married and boring to bother with how I look anymore 😉
I never iron my shirts.
I fold and roll into a saddle bag and hang them up when I can if Im staying in a hotel.
They “iron” on the body in about 15 minutes. No need to muck about.
