Sleeping under the stars on a summer camping trip sounds like a good idea until the sun goes down and the mosquito dinner bell rings. You can flee for the stuffy tent, slather yourself with chemicals or slip into a Cocoon CoolMax Travel Sheet. These thin sleep sacks, available in silk, cotton or microfiber CoolMax are impregnated with a safe insect repellent that keeps ticks, sand flies, mosquitoes and other nasties away and will keep doing so through repeated machine washings. They’re also great for warding off the chill on a long plane ride or for sleeping in that luxury beach cabana that has everything but window screens.
