Linen
Woven on Italian looms since Roman times
Flax spun and woven the slow way, then garment-washed so it arrives already soft. It creases the moment you sit down, which is the point. The crease is how linen tells you it is real.
Built for Florida heat the way it was built for the Mediterranean: it cools faster than cotton and wears in, not out, growing softer every season.
