Although a recent thread addressed rain gear, I think this general category will produce many responses, so starting another thread.
I have found Gossamer gear (google it) to be a clever approach for the slow weak older packers or the strong "marathon" packer that both want light packs. It has gotten me back into backpacking after years away. I hate feeling like a mule.
Currently use a Gossamer gear frameless pack, try to avoid taking anything that needs to be cooked and little to no tent. The Gossamer gear has an interesting solution to backpack straps-- uses socks to pad the shoulder straps, for instance.
I have no financial interest in Gossamer gear.
The cure for a fallacious argument is a better argument, not the suppression of ideas.
