A compromise — #21 of 31 Elastane ranks #21 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.
Elastane measures 40/100 for breathability, 1% moisture regain, 40/100 warmth, at 100 gsm. For hot flashes, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
