Keeping your sleeping bag dry in your rucksack is essential on a multi day trek. Our Airlok XTra 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 Xtra is good for: PipeDream 400, PipeDream 600, Pipedream 800, SkyeHigh 400 and SkyeHigh 600. The 20l Airlok Xtra is suitable for both the SkyeHigh 800 and 1000. You can squeeze the PD400 into an 8l Airlok Xtra if you work hard.
Alpkit size charts show the actual dimensions of the garments when laid flat on a table.
