Would A 14 years old use drysuits?

[Groundhog246]

But I still have a problem,although I wear my drysuits,but my fingers face and toes still cold after a long time cold water diving,I have already put on two glove and two thick socks,and what about the face?could I use full-face mask?

Wet gloves or dry? Dry gloves will certainly keep your fingers warmer that dry gloves. You may want warmer "wollies" too. If your body cools anywhere, it will "defend" itself by reducing blood flow the the extremities (fingers, toes) as it must keep your core temp up to keep your heart and lungs working and your head warm to keeo your brain functioning. So if even before you feel an all over chill, if you don't have enough main body insulation, you will start to suffer cold feet and fingers.
