Not recommended — #26 of 31 Econyl ranks #26 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.
Econyl measures 35/100 for breathability, 4% moisture regain, 45/100 warmth, at 130 gsm. For excessive sweating, low breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
