Gday all,
Since the topic is on swags or tents the obvious can be said that swags are bigger and warmer then tents, but too hot in warm months and to big at times for bikes if you use a matteress in them. Tents are too cold unless you have a sweet sleeping bag. In the end i have a simple formula i go with. If i go riding i use the tent in the attached link, this has proven itself in torrential wet season rain in Nth Qld, and kept me dry with only minor condensation within it. But this has to be teamed up with a sleeping bag. At the same time take into consideration because i do, that if you do sleep in a small tent after riding and most likely having a few or many brewskies, you wont feel the cold that much. Dont get me wrong you will still feel it, just not as much.

cheers ryno
BTW the tent packs up to about 400mm by 130mm dia, including poles. It works for me.
