... The only thing I dislike about the swags is the condensation that builds up on the inside making s/bag wet etc. Takes time to dry this out otherwise the next night is not as comfortable...
Bang on correct!!
I use a Sar Major King size Discovery, and I always sleep with the top flap closed, and the end one open... unless it's summer.
The longest unbroken stretch of sleeping in it was for 3 weeks, and when I got
home, into my own bed, I felt quite..... shall we say... naked. The swag, along with all of my clothes, ugg boots, battery, CPAP, camera bag & water bottle, is very, very cosy.
The condensation on the inside is also my problem. This is because I perspire quite easily, due to being overweight, and also having a fairly low metabolic rate. When I drive my vehicles around in the city in the winter, I generally have to use the air conditioning to keep the inside cabin air dry, because of my perspiration.
Now, I've digressed. I am considering buying a small computer fan, and a small length of flexible 4 inch tubing, say at about one metre in length. I am proposing to have the fan mounted into a small box, and simply resting on top of my sleeping bag, and drawing the moist air out of the swag.
Now, some of you may be thinking that I will be letting too much cold air inside. Correct, but I sleep very warm anyway, I just need to draw out the moist air before it condenses on the inner top of the swag, which then wets the sleeping bag. Sort of like the extractor fan in your bathroom.
Now, something else to ponder....
When I was a lad, living up north of
Woomera, we used to grow a lot of our own vegetables, but in the middle of winter, they used to get frost burnt. An old chap living with us at the time, by the name of Michael Mudie ( of Len Beadell fame ) suggested that I drape chicken wire over the plants. I did, and it stopped the problem. The wire absorbs all of the heat, and ends up getting very cold, so as the moist air passes down through it, the moisture is instantly frozen onto the wire.
This very same system is also used in some desert areas of South America to harvest water for human consumption.
I am not suggesting that we carry a roll of chicken wire with us to put over our swags, but I am sure there is a solution somewhere to stop the moisture condensing onto canvas and tarps. Maybe a rolled up fine aluminium mesh or something?
Anyway Mike, if you are moving every single day, run a swag. If you are staying for a couple of days.... tent.
I also sleep in my swag in my tent, 'cause it's my bed.
