Geeze, and here I am sittting on two pair of each that are only 35 years old (lol)
Wool 'was' the great wicker of sweat and insulator of warmth (on those cold rides) but the cost and requirements (wash/dry)doomed em after synthetics came in.
For the average rider the house brands from Performance or Nashbar can be had for as low as $19.99 and are a cold wash,hang dry setup that work quite well.
The wool always required cold water in a gentle cycle or soaking in woollite then gentlly squeezing out and laying on a towel. Todays cyclist appreciates (if not needs)the simplistic care required by synthetics.
I'd google and type in merino wool and see what comes up as far as outlets.
btw the 35y.o. wool stuff...It 'fit' when I weighed 70lbs less than I do today.lol
