Do some synthetic fills actually absorb/retain heat in a way that down doesn't, some synthetic materials actually seem to heat up/relfect heat back when you put your hand on them.Mac Ehttps://www.blogger.com/profile/11212410938991488721noreply@blogger.comtag:blogger.com,1999:blog-2910485704176747208.post-62311505969745415942009-05-24T13:46:11.617+01:002009-05-24T13:46:11.617+01:00Bags are hard to get right aren't they. Seems like...Bags are hard to get right aren't they. Seems like you do sleep cold but it's an important lesson to learn. Ratings can be extremely missleading. On the Ajunkilak web pages there used to be a link to a report on bag ratings that was put together around the time the new Euronorm was layed down. It's the most comprehensive comparison of bag ratings I've seen. I remember there being about 15 degrees between the most optimistic and the most pessimistic ratings! The Leeds rating used by Cumulus (and PhD?) was amongst the more optimistic if I remember correctly. The ratings are of course based on performance as new. I wonder how quickly top end 800-900 fill down deteriorates? In any case pperformance is only going to get worse with age.<br /><br />Chris Townsends trick of ignoring the ratings and measuring the loft is the best I think. Measure the loft on your minim and aim for something higher next time.<br /><br />I don't sleep so cold as you I don't think. I now use a Cumulus quantum 200, rated to 0 degrees, but which gets me down to about 2-4degrees depending on my mat and if I wear extra clothing. Thats the deal I make. I carry long johns and down jacket in any case so I consider them as part of my sleeping system. It's not for everyone but I figue I get a more flexible system with the minimum weight penalty.Anonymoushttps://www.blogger.com/profile/17113976429882261890noreply@blogger.com
