The Compac Dry Bag can either be used to stop water getting through to things such as clothing, but also to stop it leaking out, making it ideal for storing waders in. This dry bag has a roll top design and welded seams, to ensure that no water can get in, even should you get caught out in a thunderstorm, or the bag is standing in the bottom of a boat, for instance. The roll top design is particularly useful when storing softer items, such as clothing, as it allows you to compress the contents to minimise the amount of space the packed bag takes up. It had a 20 litre capacity and is 25cm x 25cm x 30cm in size.
