I have the basic dublin half chaps think they are about £20 and they fit my chubby little legs. I think I am on 3rd or 4th pair now - they do give as well so if you can suffer them being a bit snug for a few days . V comfortable and wesr well as well
I have the Dublin Valley chaps the xl fits my 17" calves, they also have the covered elastic inserts too, Prequestrian on Ebay is having a sale at the min on them £30 instead of £50.
I have Comfies & they really are comfy, suede where you need it & stretchy everywhere else, I got them off ebay some time ago, I think they were around £15
I have had the beautiful, buttery soft, Tuffa suede half chaps for about a year now, in Short and XL width. They fit my 17" calves perfectly, and were quite a snip at £30. They have withstood torrential new forest rain and gallons of mud, and after all that they only need a clap together and an occasional once-over with a suede brush to clean them.
