An insulated watersuit is like a normal watersuit in many ways, save that it contains far more rubber, giving it a bulky, thick appearance. An insulated watersuit grants the character all the bonuses to the Swim skill and swimming speed granted by a normal watersuit, but is designed to also protect the character from the bone-chilling cold of northern waters (or very deep waters, for that matter).
A character wearing an insulated watersuit may add a +2 circumstance bonus to all Fortitude saving throws against exposure to cold weather. The insulated watersuit is far too hot to wear in warmer climes, and will quickly become intolerably hot in any temperature above 60 degrees.
Watersuit, Insulated: 200 gp; 5 lb.
