Sealline make kit to keep your kit dry.
Let's face it, we've all had days when the heavens open and the rain just won't stop. Keeping your sleeping bag and spare clothes dry (knowing that their dry is almost as important) is essential. Sealline make dry bags, dry sacks and map cases to do just that. Compartmentalize your kit into various dry bags and stomp through the rain safe in the knowledge that dry clothes and a dry bed will be there at the end of the day.
