A compromise — #23 of 31 Econyl ranks #23 of 31 fabrics for hot flashes. It is a middling fabric for this. Ranked on breathability and moisture management, penalised for warmth and weight. The top pick is Linen.
Econyl measures 35/100 for breathability, 4% moisture regain, 45/100 warmth, at 130 gsm. For hot flashes, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
