Help, how to stop condensation between sleeping bag & swag?

Good idea
But these are kids in swags so we want to keep it cheap, simple and easy!!
But we are trying to investigate every option!!

So what is the cheapest option!!!!?

I agree with louie

We bought the swags for kids who had hardly camped... they were cheap swags (made in china) and we are now trying to solve the problem of condensation and we really think that an all cotton sleeping bag may solve it.....there is enough ventilation (large front opening) and flywire at the foot. That really it should be OK!!

He could try sleeping on his own!! LOL!!

i was just about to say the same thing Glen...Stop Breathing..hahahaha

ventilation is the secret to get rid of all that moisure one exhales .....if you let more cold air in you might need to get a warmer sleeping bag though, and get used to wearing a beanie to help keep the heat in your body and hence inside your bag

this has only happen to me when i was in halls gap or portland i could feel the condenstaion seeping into the sleeping bag.There where chunks of ice on top of the swap tho and a warm boady in side. its like driveing a car when its cold when u get into the cab the will be a slight differnt air temp and make condenstaion to solve it u wind down your window. Its the same thear.

the best bet is to say in a worm place at night somewhere in australia.

im going to look at cotton sleeping bag

if your just useign a blanket and sheeps dont they get wet as well??? or just not as bad as the sleeping bag??

Hey unko this is not New Zealand there's no "sheeps" in our swags

LOL!!!:)

Just wondering - given that the condensation is caused by the moisture from your exhaled breath - then what difference will cotton sleeping bag make

Condensation is caused by warm / hot air being cooled and as such condenses causing condensation .It is not only from exhaled breath . Body heat travels outwards until it reaches a cold surface ( being the swag as canvas is a very poor insulator )and there cools and condenses . Cotton will only absorb more of the moisture . The colder the outside the wetter the inside .

Further to Ken's answer...

I think we need to understand why condensation happens before we can attampt to deal with it.

Cold air can hold less water than hot air. (From memory ) Air at 30 degrees can hold about 35 grams of water (per cubic metre.). Air at 10 degrees can only hold about 6 grams of water.

For example - Air which is at 30 degrees and contains 20 grams of water is said to be at about 60% RELATIVE humidity. If this hot air is cooled, the relative humidity rises, even though the absolute (20 grams) amount of water in the air stays the same. This air will reach saturation point at 25 degrees where the relative humidity is 100%. Any further temperature drop will force the water to come out of the air. When this air reaches 10 degrees it will hold 6 grams of water, be at 100% relative humidity, and shed the other 29 grams of water.

When you are in a tent, a swag or a camper a few things happen. The air around you is heated by your body and your breath. Extra moisture is placed into the air with your breath. So what you have around you is warm air with plenty of moisture in it. When this warm touches cold surfaces (like tent poles or tent fabric) it is cooled and the moisture is forced out of it. This moisture clings to the cold surface and eventually starts dripping.
To prevent this happening you can do a two things.
1. Remove the moist air by ventilation
2. Prevent surfaces from becoming cold by insulating or heating them.

In my opinion, using a cotton sleeping bag will only absorb the dripping condensation. It will not prevent it.
