In reply to adman29:
I use the Theta SV, very durable salopettes, excellent quality. I find the tall fits me best but I'm only 6' so they may even come up just right or perhaps a little short!
Also be wary as they are pretty tight in the thigh, being far more athletic than other bibs out there.
The other Arc' alternative is the Alpha SV bib but they have a daft zip running through the crotch and up your crack!
It's becoming increasingly difficult to find waterproofs with longer legs, compared to earlier years!
