Dive gloves are a necessary accessory for diving, especially in cold water. Much like wetsuits, dive gloves are made out of neoprene. They protect your hands from frigid waters and dangerous obstacles such as rocks and coral. When choosing gloves, you should keep in mind what water activity you'll use them for. For snorkeling in warm waters, thick dive gloves are unnecessary and could cause you to overheat. Thin gloves are ideal and add a layer of protection between you and the underwater spectacles you'll encounter. In contrast, any water activity in cold water requires thick neoprene gloves to keep your hands adequately warm. Typically, you can choose a glove with the same level of thickness as your wetsuit. With the right glove, you can explore underwater with warm, protected hands.
