Or is it optimistic to think that a 60% wool, 40% recycled polyester jumper will be ok? I believe it will not wear well, it will bobble/pill terribly within about 3 mins of first wear, and will then be discarded, to at best, a charity shop, or maybe straight to or indirectly to landfill, as it will become an unwearable rag, despite having a price point of about 80 quid.
There are loads of them about at the moment. I know we need to recycle stuff, and I've bought a gillet that's recycled polyester. That's fine. It won't forever be in the wash, and it is an obvious nylon fabric. Great for fabric bags, etc. But jumpers? No, I think not, unless I'm missing something?
