I like the smell of my car when I leave one of my pvc macs in it, when the suns been on it, the smell is delightful.

Sealwear in Dorset do knee-length or shorter rubber bloomers in a variety of colours. I find the rubber is of very high quality and lasts indefinitely.

I can vouch for that as I have had a pair for getting on ten years now. Worn regularly and no sign of degradation.
