Since my normal kit in 1972 had a base weight under 20lbs (and I still have it), it would be considered lightweight. But it is not my normal hiking gear.
I still have clothes from the 80's that I still wear. But I will disqualify them, because I tend to buy 2-6 of items I really like. Marketing MORONS tend to discontinue really good gear.
The following I still use on almost every trip:
In the early to mid 80's I bought a Swiss Army Classic that I still use.
In the 80's I bought a Track's hiking staff. I retired it in 2009, in favor of trekking poles. They trekking pole experiment failed, and last year the staff came out of retirement.
I still use the Cammenga military lensactic compass I bought in the early 90's. This replaced a 20+ year old model. Seems there was a recall due to radiation leaks. Plus the tritium was on its 2nd or 3rd half-life.
Lots of ther gear I still use ocassionally. But those have been talked about in past threads.
