What size Airlok for my sleeping bag or down jacket?

When stuffing your sleeping bag in to the dry bag be gentle with the opening. This is the most fragile part of the bag, so avoid twisting it or putting undue stress on the internal plastic strip so it maintains a good seal when rolled.

If you intend to keep the sleeping bag in the provided compression bag rather than stuffing it straight in to the drybag you will have to choose a larger size due to the size of the opening.

Rowan from the design team spent a load of time stuff things into our Airlok dry bags here are his findings...
