Any suit cut from a cloth below 270GSM will be very lightweight. The looser weave allows plenty of airflow to keep body temperature down. If you want to wear a heritage-look tweed or herringbone suit in summer, choose one in a summer lightweight cloth from Pepper Lee. Natural fibres like linen, wool and cotton tend to be the best for regulating body temperature.
