In reply to Danbow73:
Rohan women's 'Striders' are good. I am pretty sure that we have just thrown out a worn pair but these were from several years ago and the leg was flared at the bottom - the current ones are straight and come in short sizes already, so you can take them up even more as they usually have a simple seam at the bottom. I think Striders are medium weight but you can wear some thermals underneath if there's room. We have some other things from Rohan and find them to be well made.
HTH, Jon.
