Keeping your sleeping bag dry in your rucksack is essential. Our Airlok bags are ideal for this, but which size should you go for.
Assuming you are stuffing the sleeping bag directly in the dry bag we find that a 13l Airlok is good for: PipeDream 400, PipeDream 600, Pipedream 800, SkyeHigh 400 and SkyeHigh 600. The 20l Airlok is suitable for both the SkyeHigh 800 and 1000. You can squeeze the PD400 into an 8l Airlok if you work hard.
