For those with dry gloves... are they really worth it?
This depends on what type of diving you regularly do.
The majority of my diving is in the great lakes and Ohio quarries where the water temp rarely exceeds 55F and many times is under 40F.
You also have to consider whether you normally do multiple dives and the weather.
Dry gloves on a cold/windy day surface interval can be real nice.
Since my diving regularly combines both of these situations.... I have and love my dry gloves.
