Weatherproof sock fabric

I knit a good swatch from 3-ply, 1,680 ypp yarn on 1.3 mm needles at 12spi & 20 rpi, fulled it, napped it, oiled it, put it on the counter, and poured water on it.  

The water stood in a pool on the swatch.  

The fabric passed the test.

• The Sheringham ganseys are weatherproof. 
• Knit Tudor hats were likely weatherproof.
• We can knit all kinds of stuff out of  "sock yarn" to produce light, elastic, and weatherproof objects.  We can knit socks that will really help our feet stay dry.
• Joyous Rapture! 240 stitches of knitting joy per square inch! We can get more knitting pleasure per gram of wool.
• I believe the yarn is flock run Cheviot, spun worsted, with a soft twist.

I expect traditional hosiery yarns to perform better.
