    I didn't see (after a quick search) thread like Shelter news here, so I thought I start one. If there's one, please move this to it.

    Draft collars now on EE quilts.

    So since I have a bit too much time on my hand, I made a very unscientific spreadsheet which shows the weight/R-value ratio with lower the value better the ratio. Make of it what you will...

    Just a thought but maybe sort the row order. So lowest wt/R at top to highest wt/R at bottom. Just trying to help you mitigate the time xs problem ;)

    My MS Office doesn't work anymore in Catalina (and I'm not buying a subscription service) so I'm trying to get grips with Apple's Numbers (spreadsheet), so I'm not as handy with this as I'm with Excel, but here goes. With a bit of effort, one could add price of the pad to get a weight/R-value/price ratio ie what's the lightest, warmest pad for the price. Getting a bit geeky now...

    This new standard must be flawed though? I'm fairly sure my exped hl and sts ul insulated are similar warmth to the xlite I had. Maybe the reflective layers are messing with things? I mean 4.2 is really a getting into winter ratings and I've seen plenty reports they aren't great warm much below freezing.

    It looks odd doesn't it. Under the old ratings the Exped Synmat UL was just a bit less R than the woman's XLite, so it was really a question of which style mat you prefer and paying a weight penalty for the comfort. Under the new ratings the women's Xlite has nearly double the R of the synmat which scores really badly. It makes the synmat UL look very poor on both R value and weight. But they are widely loved.

    Thanks! A good resource.

    Nice work. Ta.
    Read on BPL I think, to get something like the 'true advertised' thermo value of your bag/quilt your mat must be at least R 4. Recently using my new Cumulus quilt 'rated' to 6 on an Xlite I get this with lightish thermals. Sort of lead me to keep my Xlite rather than go an Xped -even though I wanted to try the Expeds comfort. I bought it under the old regime but as an Xtherm owner as well, it always felt 'warm' to me in comparison. Warmer that is than I might expect at R3.2. Know someone that uses the Xlite with the 2mm reflectix stuff ski touring every winter. Potato chips ahoy!?
    Although can't say that anymore- it's pretty quiet.
    The Xtherm feels far warmer than the STS equivalent (which has gone down from well over R5 to just R4) which I had and sold.

    Interesting, but I go lightweight over R value, and if it's really cold slip my emergency blanket on top of my mat (Xlite) - much warmer, although the noise is a bit of a downside.

    Yup, I haven't arsed much yet, as I haven't needed to use spreadsheet that much.

    Maybe it's transitional kit from mummy bags to wide quilts? Or maybe for summers it's worth while opening the zips for better airflow and winters keep the bag as tight as possible to minimise the internal space that needs to kept warm.
