I backpacked and climbed a lot from 1970-1990 using a heavy-weight approach. In the 1990s other things filled my time. In 2001 I was again backpacking, but with a light weight approach. Most of my trips are to the sierras with a base weight around 9lbs. I did a lot of gear testing between 2001-2010. Since then my kit hasn’t changed significantly… mostly clothing being updated because the previous items wore out. Used to be very active on this site, but these days try to maximize my time outside.
