A solid choice — #14 of 31 Chiffon ranks #14 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.
Chiffon measures 78/100 for breathability, 8% moisture regain, 20/100 warmth, at 50 gsm. Wool fibres lead here: Chiffon is not a wool fibre, so it leans on breathability alone.
