Not recommended — #24 of 31 Elastane ranks #24 of 31 fabrics for night sweats. It is a poor fabric for this. Ranked on breathability and moisture absorption, 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 night sweats, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
