These socks are 40% possum fibre which perfectly partners the 50% merino wool (and 10% nylon for strength). This wool is lightweight, instantly warming but not overheating, and makes GREAT socks!
Very interestingly the possum-merino-nylon mix can be happily laundered in the washing machine at 30 degrees (wool wash) BUT as possum is odour-eating and merino moisture-wicking the socks do not need washing so often (truly!). Calf length.
The 'plain sole' refers to the difference between this sock and the 'cushion sole' variety - which does a completely different job! The plain sole socks are good, every day socks, for shoes, wellies in the summer (sadly, but you probably know what I mean) or even bed-sock replacements.
Colours as per graphic.
