waterproof trousers

[bighit]

As above, miltary surplus Goretex is best, but if you're looking for something a bit more industrial, Flexothane, 100% waterproof but not breathable or particularly tough, it's commonly what you will see being worn by farmers, construction workers & suchlike.
Both of them are on the noisy side.

Hoggs of fife brought out the working climate range to entice farmers to use their garments . An army looking wind stopper jumpers , waterproof jacket and trousers. They used Gore-tex. I got samples to try and I still have them .

The jumper is great and the water proofs live in my shooting bag.

Don't think they do them now.
