I just spent a pretty wet weekend in the woods of Pennsylvania, which caused me to start thinking about ponchos. My gore-tex knock-off jacket, pants, and boots did a pretty good job of keeping me reasonably dry, and I was especially impressed with the boots. However, by the end of the day, I was damp through and through, either from minor condensation or from minor seapage. With temps in the mid 40's, I was also pretty miserable.
Back in the days before gore-tex, I had a big poncho that my wife sewed from a kit that came from either Holubar or Frostline. The thing was completely waterproof, and the open design allowed some ventilation. It also covered my pack, which was nice.
Why don't I see backpackers using ponchos anymore? It seems to me that there are some advantages to a poncho - light weight, less complexity (no zippers to break), ability to be used as a tarp in an emergency - but that backpackers, at least "serious" backpackers, seem to have abandoned them. Am I missing something here?
Thanks for your thoughts.
