In reply to captain paranoia:
"Yes, I know who did the research, and I'm familiar with the work and reputation of Leeds."
Excellent! So you'll have no problems excepting the research? Or are you prejudiced because the words are printed in a magazine you choose not to like?
"my primrary objection is the variation"
Well why not test it? you could proof one jacket with comfort and one with a branded product and do a test in real conditions, bring a mate along or maybe two and have a control.
I've been using non-branded products that make "towels look fluffy" for a number of years, not just at weekends but f/t in the full spectrum of conditions and I've found my anecdotal experience backs up Leeds research published in Trail. Yep, pure soap and the right comfort last about 30 hours of use.
But I'm keen for people to pay full price for branded products as a small percentage will get put back into R & D and hopefully improve the products and then I might go back to them. So please do not tell anyone else, lets keep it a secret just like the BMG who told me about pure soap flakes in 1993. SSSHHHHHhhh!
Its interesting that such a shockingly kitch magazine such as Trail keeps on coming up with such relevant information, not just DWR and proofing agents but the UV resistance of tents. Other 'series' mags never seem to run such articles. Wonder why?
