Waterproof bag for your wetsuit With this handy wetsuit dry bag from Mystic you can take your wetsuit with you everywhere without the rest of your stuff getting wet by your wetsuit. The wetsuit bag is transparent and large enough for one wetsuit. The wetsuit bag can be closed watertight by turning the top of the bag several times and then securing it with a clip. You can of course also store your complete winter equipment here, including your cap, gloves and neoprene shoes.
