FW,
That suit will do you just fine at Vortex, throw on a thin hood and some thin golves and you'll be walkin the walk and talkin the talk . . .
Oh, by the way, FW, make sure you take something to wear over your w/s during your S/I. The wind gets to be a bit brisk coming across the spring basin this time of year.
In fact, if you can borrow a dome tent from a friend, that would be even better.
The Yellow Angel Fish and I were down there a couple of weeks ago to do an OW cert. We took our dome tent because we knew it might be a bit chilly. That was a GOOD move!
Connie, Erica and the crew have no problems with letting you set up a tent over by the picnic tables in order to stay out of the wind. Make life much more pleasant this time of year.
