My 10 years-old overtrousers were no longer doing their job, and for me the replacement had to be olive colour or similar, I do not want black ones which are commonly available.
After searching high and low on the net I bought a pair of Champion 'Typhoon' waterproof overtrousers which are the colour I want, allegedly breathable (I haven't used them in any serious rain yet) and they were only £9.95 (plus rather overpriced p&p).
They are pleasingly lightweight, only 205g plus a 15g bag, a good fit for my waist and legs and they have slits for access to trouser pockets (but no fly). The zips are long enough to get them on and off over my boots, something I was a bit anxious about before they arrived because I once had some cheap Regatta ones whose zips were too short.
If I get just a year's use out of them I shall be satisfied for that price.
The only thing that has ruffled my feathers is that the country clothing seller has since emailed me every week asking me to review my purchase, for which they're not getting one.
