Not recommended — #26 of 31 Econyl ranks #26 of 31 fabrics for odour resistance. It is a poor fabric for this. Ranked with a wool-family bonus plus breathability and moisture management. The top pick is Merino.
Econyl measures 35/100 for breathability, 4% moisture regain, 45/100 warmth, at 130 gsm. Wool fibres lead here: Econyl is not a wool fibre, so it leans on breathability alone.
