Gear ultralight gear
The Ultra-Sil Tarp Poncho is great for keeping your pack weight down. I use mine with a hammock in the summer. Instead of packing raingear a packcover and shelter the tarp poncho is all I need. The tarp coverage is adequate for mild weather but I'd want something larger if I expected to encounter more severe weather.
I keep one of the plain nylon versions in my truck for emergencies. I'd also recommend carrying one on day hikes as lightweight insurance in case you have to spend the night outside.
