Yes, it does, and it's because of the cap's material. While silicone and neoprene caps are strong and recommended, they tend to hold heat. So there's a chance of your quickly overheating while swimming in water that's 80 degrees or warmer.
Latex swim caps are a better choice while swimming in lukewarm temperature water. They are thinner and don't retain heat as much as neoprene so that you can swim better.
