G'day Stephen,

Your best bet will be to go for the compression dry sack if you want to take your treeline hiking and ensure it will be dry and compressed. The Medium Compression Dry Sack will suit the Treeline.

G'day Ross,

The dimensions we've got on the Sea to Summit Lightweight Dry Sacks is before you've rolled them. As for the length once rolled and sealed, it all depends on how much you roll them down. You could keep rolling until it's less than half if you wanted to, or you could just roll it once or twice. 

G'day Ross,

Rolling the bag 3 times, I still had a length of a fraction over 60cm, so you should be pretty safe.

G'day Alison, 

I've just had a look at the stock we have downstairs, and it looks like the Sea to Summit Lightweight Dry Sack doesn't come with a handle. However, this brand does make a Sling Dry Bag in a 10L, and 20L which you might want to check out. 

G'day Simon, 

That's spot on, although I find it's sometimes good to get a slightly larger dry bag so that you have extra roll top space for sure fire waterproofing and don't waste any internal capacity once you have it all packed out. So having said this, you could use the 35L in the Tempo 30 happily as you can always just roll out any extra space.
