Losing sleep because you’re cold and uncomfortable can ruin an otherwise amazing camping trip. In addition to getting a tent for your appropriate ventures and temperature range, Purdy has some tips and tricks you can employ to make your experience comfy and cozy. “First, make sure you also set up your tent’s rainfly (the highly waterproof outer shell). This will help keep the chilly wind out and your body heat in. Second, an inflatable camping mat combined with a good quality sleeping bag goes a long way to keeping you comfortable all night. On very cold nights, you can also fill a Nalgene bottle with warm water and throw it in the bottom of your sleeping bag, this will work wonders for keeping you warm,” he says.
