| I thought about this too.
I opted for a good 2 piece semi (7 mm) - beaver icelandic ultra
I dont feel the cold too much and its fine for most of the year in the uk, plus i can just take 1 piece on my hols.
A dry suit is great for diving all year round... BUT that comes at a price!
AND when it leaks (which it will do eventually) it can be bloody expensive to fix.
A dry suit is also a bit more difficult to dive in (i find anyway). But like all things it takes practice.
I sugest trying out a few before you buy |
