Windshield Reflector Question

[QUOTE=BushcraftHanger;853306]I would only plan to go on trips with 40 degrees or above nights.

Just for what it is worth, be careful, when thinking about minimal temperatures you might find yourself in. You might expect something around 40 F. however weather is a little fickle, you might end up in something colder, be sure you know how to take care of yourself if you find yourself in a colder enviroment than you expected.

The two places I live, we are always having people get into trouble when they are out enjoying nature and the temperature drops suddenly and totally unexpectedly. We all need to be prepared for the unexpected, one never knows what might happen. Snow and such can show up in the oddest places.

I remember the Cub Scouts that all drowned in their sleeping bags, while camped next to a lake in Montana. Nature is tricky sometimes. Be prepared.

The best idea I've heard for a windshield reflector is selective placement against cold spots.

P.S. I defer to the experience MarkI describes below.

This past summer I used a windshield reflector that used bubble-wrap for the insulation layer and got some serious cold spots to go with the condensation - the wind off the cold lake up here in Canada may have been partially to blame. I've heard that the ccf-cored reflectors work much better.

I use underquilts, but I sometimes took a piece of windshield reflector for extra warmth when pushing my 40° UQ. Last time I used it the low was probably 30°. I was using my 20° synthetic sleeping bag - there was a ton of condensation when I woke up at 4AM. That's too bad because these things weigh nothing and take up little space in the pack against your back.

Were you laying inside the sleeping bag or directly on top of the reflector? I noticed a lot of condensation under my bag if I slept inside it. Laying directly on the reflector with the sleeping bag as a top quilt resulted in no condensation for me.

I was sleeping in the bag with the pad between the layers of my hammock. I never thought about laying right on it. But since then I got a 20° Incubator, so I don't think I'll be using it anymore...at least as hammock insulation.
