These tent cots are not meant for cold weather at all, people usually use these with cold weather sleeping bags. If you’re going to be camping in 20F weather, then you’ll definitely want to grab a sleeping bag that provides good insulation in low level temperatures. These are very easy to come by and can be affordable. You can grab these in addition to a tent cot that provides protection in rainy weather, to ensure that you’re getting the best protection when you go camping.
