Proper attire for sleeping

In cold places it is customary to wear pajamas for protection against the cold. But in tropical countries, the common attire for sleeping during camping trips is the shorts and tee shirt which is loose so the body will be ventilated somehow. Hat are not usual here although I saw some campers wearing caps maybe because the are bald. My uniform for sleeping in the tent is the jogging pants with thick fiber so it can protect me from mosquitoes and other insects. For the upper body it is always the pajama with thin fiber for ventilation. I wear bedtime uniform regardless of the kind of weather.

 

... how bout commando? "Just sayen". It really depends on the environment and personal style. When I hop into a sleeping bag I don't want to feel congested or get myself tangled up at night.
