I would get it fixed if it's a Henderson. In the meantime get one of these. Great for hot nights, inexpensive, and it will more than get you by. I actually prefer them over the hyperstretch suits.
How do you keep your arms warm in one of those get-ups Luds?
Just an under armour shirt. It's all you need in the summer. Obviously it woud be cold in the cooler months. Surf tops work well with it too but they are not cheap. The nice thing about a farmer john is it wears nicely with a dry top also.
