The May long weekend is often the start of camping season and as I am writing this it is -2°C. If you are sleeping out in the elements have a warm sleep with a Spring to Fall three-season sleeping bag rated between -1°C and -20°C.
Caution! Often sleeping bag ratings you see are extreme ratings meaning that if all other circumstances are perfect then this sleeping bag will keep you alive at that temperature. Keep in mind that there are many factors that go into staying warm at night. We recommend using a sleeping bag that is designed for colder than what you will be sleeping in.
