All this is fascinating, it really is... But I have about three light fleeces that I wear under my jacket (one at a time) for work.
Between them (all three that is) they cost thirty quid. They have builders silicone on them in places, ones got a bit of paint on the shoulder where I leant against a wall. I'm not fussed about that because they are just cheap work clothes.
Now woollen jumpers just can't compete with that price, I doubt I could get the wool for that.
If you lot want to extol the virtues of a plastic free lifestyle that's fine by me cos I'm pretty sure not being able to tap the words out on a placky keyboard will lessen your output a bit...
I'm happy for you people who go out for a single day or so wearing all natural materials and you stay warm and with Ventile you stay dry (ish) but as soon as January starts I'm putting the roof on a lifeboat station and you can keep all the natural materials in yer bleedin tinfoil covered bug out bags, next to the massive heap of carved spoons you obsess over cos I'm wearing the brightest orange Gore Tex imaginable with fleece underneath.
I can't be done with things that require too much time to dry out (Ventile) or fancy washing (wool) or cost a fortune (both of those) compared to something that just works.
As for the "Be a Mensche" thing? Riiiiiiiiiiiiiight...
Ex army wooly pullies can be had for very little, Charity shops can have great wool items for pennies, most washing machines have wool programs..... and your other arguments are...?
