Not recommended — #31 of 31 Acrylic ranks #31 of 31 fabrics for hot flashes. It is a poor fabric for this. Ranked on breathability and moisture management, penalised for warmth and weight. The top pick is Linen.
Acrylic measures 35/100 for breathability, 2% moisture regain, 60/100 warmth, at 220 gsm. For hot flashes, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
