Here's what I thought of straight away

Now this may already be a thing? But with this recent heat it's been hot in the coppice with a hat on so I figured a fan in the hat could be useful.

 

So far I have it down to using a 9v notebook fan with a switched 9v battery holder with rechargeable battery's in it.

 

But where to place it in the hat for best airflow? The back would be good but maybe on top near the vents?

 

We used these on the farm in the grain bins. A filter round the back of your neck keeps out the dust and a fan blows air over your face.

They were not cheap but you might find a used one on eBay

Think it's all sussex, parts on order now to wait and then get to modding my husky hat with the set up.

We used to use the airstream ones in the foundry I worked in and they didn't cool any more than the ambient temperature there is a filter at the back and a further tubular one over the top of your head to direct the air down your face so you don't breathe dust.
