A solid choice — #12 of 31 Viscose ranks #12 of 31 fabrics for odour resistance. It is a good fabric for this. Ranked with a wool-family bonus plus breathability and moisture management. The top pick is Merino.
Viscose measures 70/100 for breathability, 13% moisture regain, 25/100 warmth, at 150 gsm. Wool fibres lead here: Viscose is not a wool fibre, so it leans on breathability alone.
