Not recommended — #27 of 31 Elastane ranks #27 of 31 fabrics for excessive sweating. It is a poor fabric for this. Ranked on breathability and moisture handling, penalised for weight. The top pick is Merino.
Elastane measures 40/100 for breathability, 1% moisture regain, 40/100 warmth, at 100 gsm. For excessive sweating, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
