What is the purpose of watertight seals on the dry suit?

• A. To improve fit around the waist
• B. To keep water out at the neck, wrists, and ankles
• C. To attach gloves
• D. To inflate the suit

Answer: (B)

The main idea is that watertight seals are there to block water from entering the suit at the openings. The seals around the neck, wrists, and ankles press against your skin to form a barrier, keeping the interior dry. Staying dry inside the suit is crucial for warmth and comfort in cold water, and it helps maintain the suit’s insulation and performance as you move. Water inside would rapidly strip heat away and make the suit less effective.

The other options don’t describe the seals’ purpose: the waist isn’t primarily about sealing for fit, gloves are not attached by the seals themselves, and inflation of the suit is done through a separate valve system, not by the watertight seals.
