From what I understand you just layer up the baby inside the bag! Mine came with a little thermometer that tells you what to dress your baby in according to the temp. e.g if its 18degrees then the baby needs a 2.5tog and longsleeved bodysuit aswell as a sleepsuit/pyjamas. But at 22degrees its a 1.0tog and just a longsleeved body suit!
The only thing I find tricky is the temp drops so much in the night, so I dress my baby for the temp at its coldest.
