After two previous attempts, I finally got some Gore Windstopper leg warmers that fit.
The 1st pair were M (like my failed pair) but I couldn't get them up my far from massive thighs.
The 2nd pair were L and were very tight but also too short.
These are XL and they fit very nicely at the top of my legs but it's a little bit of a struggle to get them over my calves and my calves are quite skinny.
It's lucky that I no longer play football; my legs have shrunk considerably since I stopped.
Strange that Gore don't expect cyclists to have leg muscles ............
Praise to Bike 24 for having good prices and an excellent returns system
After today's windy ride home from Helen's, I'm thinking about a pair of Windstopper arm warmers.
I just need to decide on the size
ETA: there's an excellent sewing place in Whitefield and they managed to fit a new zip to the old pair so they've been given a new lease of life.
