* Speedos: Speedos are a type of swimwear that is typically worn by competitive swimmers. They are designed to be restrictive and provide minimal coverage, which can help to reduce drag and improve swimming performance. However, speedos can also be uncomfortable to wear for long periods of time, and they may not be appropriate for all body types.
* Swim trunks: Swim trunks are a type of swimwear that is typically worn by recreational swimmers. They are more comfortable than speedos and provide more coverage, making them a good choice for people who want to be able to relax and enjoy their time at the beach. However, swim trunks can also be less hydrodynamic than speedos, so they may not be the best choice for people who are planning on doing any serious swimming.
* Traditions/culture: In some cultures, it is more common for men to wear speedos to the beach, while in other cultures, it is more common for men to wear swim trunks. It is important to be respectful of the local culture and customs when choosing what to wear to the beach.
* Location: The location of the beach can also play a role in deciding what to wear. If you are planning on swimming in a public pool, for example, you may be required to wear a swimsuit that meets certain standards of modesty.
Ultimately, the decision of whether to wear a speedo or swim trunks to the beach is a personal one. There is no right or wrong answer, and the best choice will depend on your individual needs and preferences.
