A compromise — #17 of 31 Viscose ranks #17 of 31 fabrics for quick drying. It is a middling fabric for this. Ranked on low moisture regain, low weight, and packability — the inverse of absorbency. The top pick is Polypropylene.
Viscose measures 70/100 for breathability, 13% moisture regain, 25/100 warmth, at 150 gsm. Fast drying favours low moisture regain: at 13% Viscose holds water and dries slowly, and 150 gsm keeps it light.
