Swimmers wear 2 caps to improve their results.
In swimming, fractions of seconds really do matter, which is why athletes do everything to become even just a little bit faster. For example, they shave their entire bodies to decrease the water resistance and wear very light goggles. They also wear 2 caps.
- Because the caps allow them to keep the goggles on better. First, they put on the first cap, then the goggles, and then the other cap.
- Because it helps them to decrease the resistance. The first cap is made of latex which has wrinkles on it. On top of it, they wear a silicone cap which is not that comfortable but has fewer wrinkles on it.
