Not recommended — #30 of 31 Recycled Poly ranks #30 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.
Recycled Poly measures 32/100 for breathability, 0% moisture regain, 50/100 warmth, at 140 gsm. Wool fibres lead here: Recycled Poly is not a wool fibre, so it leans on breathability alone.
