Shimano pogies are mentioned three times on the first page of this thread but I can't seem to find them even here in Japan.

But it is okay. I cut off the sleeves of an old wet suit and made myself some "Bar Sleeves." I may make them more "Bar Mitt" or before that "Mouse Mitt" like, or add them to my collection of ridiculous looking useless things (before anyone asks stem, and specs).

An added plus is that I did not use the wetsuit because I have given up wakeboarding and it was too thick to swim in. Now it is an armless wet suit, it may get some use for winter swimming.

Thanks for the Zzipper farings link. Good idea. They even make you faster (or at least more efficient) apparently!
