| Aug 29, 2017 at 13:58 | comment | added | Tullochgorum | @Liam - I think that Alpkit protests too much in your linked article - they are a low price manufacturer that is trying to justify the fact that they aren't shelling out for the expensive testing. As I said in my post, it's a rough and ready measure, but certainly not meaningless. A pad rated 6 is going to be far, far more insulating that a pad rated 2. But as I said, it's only a starting point - you have to do your own field testing to find what works for you and the conditions you camp in. | |
| Aug 29, 2017 at 13:57 | comment | added | Tullochgorum | The R-Value is an arbitrary scale, as I understand it.As I say in the post, anything under 2 or so isn't giving you much insulation, while you should be looking at 5+ for cold camping. If you want to know the nuts and bolts you'll have to google it - I'm not an expert. | |

Can you please specify the units for your R value? m²*K/(W*in)? ft²*°F*h/(BTU*in)? m*K/W? Or are you using an integrated quantity? Units m²*K/W, ft²*°F*h/BTU, or m²*K/W? For an international audience it may be optimal to specify it in all three (metric, US Customary, and this strange mixture).
