True or False: The dry suit must never be worn over regular clothing.

Wearing a dry suit over regular clothing is acceptable and indeed common, provided that the clothing is appropriate for the conditions and does not hinder the suit's effectiveness. Dry suits are designed to keep you warm and dry by creating a waterproof barrier, trapping insulation while allowing for layering underneath. Under the right circumstances, clothing can enhance the insulation properties of the dry suit.

The choice of what to wear underneath often depends on the environmental conditions, the specific activity being undertaken, and personal comfort. Lightweight, moisture-wicking materials are frequently recommended to prevent any sweat accumulation that could lead to discomfort when wearing the dry suit. Therefore, the assertion that a dry suit must never be worn over regular clothing is incorrect; it can be effectively worn over suitable clothing for protection and heat retention.
