G'day David,

The Darche mats would be suitable - they're fairly new to our range, but are increasing in popularity.
I don't think you'd have to many issues and it will probably increase that comfort for you well.
The roof top tent sleeping space is 230cm long, but you wont get a mattress that is that long anyway.
Might be good to have abit of storage space for a bag, etc if needed.

G'day Mick,

Being a bonded self inflating mat, you shouldnt have any issues storing this rolled up in the swag.
The best outcome is deflating the mat as much as possible prior to rolling the swag up.
You should still be able to fit the whole packed swag back in the swag bag, no issues.

G'day Romy,

We can't sorry - Darche haven't done any insulative or R-Value rating testing on their mats.
Go off mat quality and brands who produce a similar mat we'd say its around 7-8.

Hope that helps.

G'day Mark,

Yes this mattress should fit inside the 23Zero Dual 1100 swag, the swag sleeping area is 205L x 110W cm so it would be nice and snug. You can leave the mat inside a swag and roll it up, you would just want to make sure it's deflated before doing so and free from any rocks or bits that may poke the mat.

The mattress does fully self-inflate, as with any mattress the first time you inflate it can take around 2 days to fully inflate and can require some extra air to get it to shape after being compressed from manufacturing. After this first time, it usually inflates quickly. Darche don't recommend using a pump but you can use your breath to put some more air into it.
