A compromise — #18 of 31 Canvas ranks #18 of 31 fabrics for night sweats. It is a middling fabric for this. Ranked on breathability and moisture absorption, penalised for warmth and weight. The top pick is Linen.
Canvas measures 55/100 for breathability, 8% moisture regain, 50/100 warmth, at 380 gsm. For night sweats, modest breathability and limited moisture absorption decide comfort — and its higher warmth risks trapping heat against the skin.
