When choosing open water swimming caps, there are a few things to consider. The type of swimmer, the activity, and the type of cap. The swimmer is the most important consideration when choosing an open water swimming cap. If you are a beginner or intermediate swimmer, choose a flexible cap that fits well. If you are a more advanced swimmer or bodybuilder, choose a more rigid cap that provides better protection from the sun and chlorine.
A second consideration is an activity you will be participating in. For example, if you are swimming at a pool party or beach party, choose a less protective cap. On the other hand, if you will be swimming in open ocean waters or in cold water lakes, choose a more protective cap to avoid hypothermia or drowning. The type of cap also matters when deciding how much protection it offers.
