Environmentally friendly hat?

[hugoagogo]

I've always been conscious of how my actions and purchases affect the environment. Now though things have really ramped up and every purchase is fraught with guilt and indecision.
What a selfish bastard I am buying a yoghurt!
Anyway, I digress, I need a thin soft hat that covers my ears. I have had primark acrylic ones in the past, but now can't overlook the environmental cost.
Any ideas?

Natural fibres! I have a wonderful very thin recycled cashmere one from Turtle Doves. (www.turtle-doves.co.uk/collections/cashmere-hats)

Those cashmere ones are very plain looking for the money.
Is cashmere ok? I have been reading a lot of horrific stuff about sheep's bottoms- are the goats treated any better?

You could buy a second hand one in the style/material you like.

Turtle Doves ones are all made of up-cycled cashmere to reduce environmental impact, which is why I personally like them. H&M and COS have them new, their sustainability policies are available on their website.

I think anything made out of natural fibres will be better than acrylic, but reusing or up-cycling existing natural fibres is even better!

Why not knit one? Or get someone to knit one for you. If you don’t want to buy yarn, repurpose a hand knitted garment or get something from a charity shop to unravel and redo.

If you want a thin one, 3 or 4 ply yarn should do.

There must be an easier way to get a non environmentally damaging hat than spending £30+, knitting my own or searching high and low for a used one that I like!

Ethical also means everyone in the process is paid fairly so that will bump the price up.
Knitting isn't tricky though crochet is easier and faster especially for hats.
