That would be my guess as well. The OP is wearing multiple layers, and air can get in beteeen easily. I wonder if the problem is still there after thirty minutes of diving. With the tank somewhat lighter then, it should be worse, but if the air from the suit, BCD, etc is then gone, re-descending would be easier.A LOT of air can be trapped in the suit at the beginning of a dive...as stated, try pulling on the neck seal to flood the suit... it can make a substantial difference!
