Don't let age be your enemy. Invest in HGH it works wonders.
The stuff that was around in 1980 was expensive and no where near as good as todays gear. I worked outside back then, a gortex coat was un heard of unless you had $$$ to drop on it. Wool was the way to go and some of the early synthetics, doufold made one that was blended with wool, capielline was a product of the Polar fleece revolution of the 90's. The stuff back then was crap.
