Dear Tom,

Am I right in thinking that the zippered armhole
in the picture is the faint, dark, descending
curve that goes across your upper arm?

I added armholes after this picture was taken. Armhole slits are
generally very close to horizontal.

And come to think of it, how do you get into
it? It doesn't look as if you could seat yourself
and then pull it back over your head or forward,
so maybe it's stretchy enough to pull up and
get in from the side? Or does the zipper along
the top let you step in from the top?

Entry is from the side - kneel by the bike, duck head under side of
sock, stand up inside sock, lift leg over frame, sit down, zip up.
Egress may be aided by temporarily disconnecting the sock at one of the
lower rear corners.

Do you have a web page for this kind of body
sock? Experience suggests that I'll end up with
hundreds of women wearing leotards while bicycling
if I try to search for it myself.

This is the company that manufacturers bodysocks for Easy Racers (and a
few other bikes).
