Both the basic and advanced are warmer than a woobie - that's a standard issue US military poncho liner. I wouldn't rely on either along outside of good weather in summertime. Two together get me down to about 0 deg Celcius (32 def F) in a shelter. When I use these outdoors, the Swagman is used as a liner inside some other kind of bag.
