So in my experience the things that help us Southern boys cool off at night are:
- Camping near water, Open water such as a lake creates a small costal wind effect where as camping near a river seems to create a steady wind direction all night.
- Place a wet bandana or pack towel over your chest and the evaporation of moisture will work like a heat pump helping pulling heat from your body.
- A small battery operated fan hung from the ridgeline creates a steady breeze tillt he batteries run out. Try hanging it at one end so that it blows over your entire body.
- If you can't afford the batteries for the fan, because lets face they can get heavy in your pack, find a nice Southern Baptist grandmother to go camping with you and setup down wind of her church fan. Because let's be honest they can really get those things going.
Even the lightest of breezes feels great in a hammock, and although we need the bugneting in the hottest of months, we can still stay comfortably cool with good site selection and some forethought.
