I had not seen this! Bravo!! Brilliant study and quite surprising, actually! I, like others, would have innocently assumed that more yardage = higher R value. Very interesting indeed! Any plans to further your research with the new gadgets your publication afforded you? I'd love to see some of the suggestions on the original thread covered (i.e. p@nts, different wool weights, temperature at the knee, etc.). All in all, well done and congratulations on being published! Well deserved, I say!
