A compromise — #20 of 31 Hemp ranks #20 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.
Hemp measures 90/100 for breathability, 12% moisture regain, 20/100 warmth, at 200 gsm. Fast drying favours low moisture regain: at 12% Hemp holds water and dries slowly, and 200 gsm keeps it light.
