I assume you're asking dry top vs full dry suit? The answer is, YES.
As others pointed out, as long as you don't swim, you'll be fine. And as Jay pointed out, swimming is usually not mandatory even if you're not 100%.
If you do swim, you'll of course be cold. But if you're just practicing, you'll be near shore anyway. No big deal. And if you're dress warm to begin with, that short immersion shouldn't bother you at all.
(you need some warm clothes under the dry top. Even without swimming, you still feel the cold water full on when you're upside down. That's true whether you're in dry top or full dry suit) |
