Hi guys

I've been up the mountains testing tents and mats, and out of contact.

Let me emphasise: all the figures quoted for mats are SI units. I don't know right now what the R-value is for aerogel, and will need to look it up. Right now I am my daughter's place for dinner on the way home, and not really in 'back on earth' yet.

It was meant to be an Autumn light-weight walking trip with light joggers .... We got ~8" snow on the last night and getting off the mountains via a long backcountry dirt track was 'interesting'. We had the chains on the 4WD for a LONG time. Not quite what the weatherman forecast, but that is totally typical for around here.

Tents and mats survived the experience, so all was well.

Cheers

Aerogel R-value on 05/11/2011 02:38:08 MDT Print View

From Wikipedia:
'It has remarkable thermal insulative properties, having an extremely low thermal conductivity: from 0.03 W/m·K[9] down to 0.004 W/m·K,[6] which correspond to R-values of 14 to 105 for 3.5 inch thickness.'

Glad to hear you are heading safely back to your hobbit hole.

Looking forward to reading the results of your testing of the tents and mats.
