Thankfully we've had a bit more rain round here of late to test my wool's waterproofness, if that's a word.
To answer squidders' point first, the theory I'm hoping to test is that with layers of wool, even if water soaks through you remain comfortable and warm.
Anyway, I've recently enjoyed a couple of three hour walks in pretty consrant and fairly heavy rain with my trusty wool duffel, a wool medium weight jumper underneath and a wool base. Again I have been quietly amazed at the duffel!s ability to keep out the water.. Iti isn't particularly thick but fairly densely woven and the inside of the fabric was dry, even on the shoulders after my jaunts.
Nothing appeared to get through to even the mid layer never mind the base layer. Afterwards the coat was wet and remained wet overnight and well into the next day but at no stage was it uncomfortable to wear, which is the main point I think.
I plan more stringent tests when the weather allows ans when it really chucks it down I will wear a wool cape over my main outer layer which I hope will do the trick.
Thanks guys for your interest.
