I'm looking for something lightweight/low bulk to keep the chill off when camping in spring and fall. It seems a lot of people like the poncho liner, but how does it compare to a simple fleece blanket? This would normally be used either backpacking or paddling to the campsite. Temperatures would be 60's-70's F.

1. Will a wet poncho liner still keep a person warm?
2. How small can an offical US military poncho liner be scrunched?
3. How dangerous are flames/sparks/heat to a poncho liner?
4. Anything else you think I should know?
