Storing Your Mask, Snorkel, and Fins
Heat, humidity, ozone, and ultraviolet rays are part of any dive day. But over time, these can harm the rubber and silicone your skin gear is made of.

To prevent these elements from damaging your skin gear, store it in a cool, dark, and dry place. If your mask came with a storage case, use it to protect the mask's skirt. Hang your fins or lay them flat to prevent warping. Allow the gear to dry completely before storage to prevent mildew from forming.

Storage between dives is equally important. Gear should be kept as clean as possible, and away from direct sunlight. A short period in the sun can soften the gear and cause permanent deformation. For example, leaning your fins up against a wall exposed to direct sunlight could permanently warp them.
