Going to Hawaii in April

[thalassamania]

I would be cold in a 3 in Hawaii. I always take my 5, and in winter my 7.

It all depends on your tolerance and what you're used to. I dive all the time in very warm water, so if it's a bit cooler I'm uncomfortable and like to have more rubber.

We were diving two days ago with no suits what-so-ever. A dash cold getting in, but fine after a minute or two, 45 minute dive, no problem.
