G'day Aiden,

If you've got the Oztrail Mitchell Expedition Jumbo Swag, then yes the Outbound 1100 Swag bag will do the trick.

G'day Paul,

The Outbound Swag Bag is made from Darche's 420gsm poly/cotton ripstop canvas, there isn't a specific UV stabiliser used so overtime the canvas will fade and degrade due to UV exposure. We wouldn't recommend leaving it on your roof rack permanently.

G'day Ryan,

You shouldn't have any troubles fitting your 1100 x 70 mattress into the Outbound 1100 Swag Bag. 

G'day Rick,

I've just checked them each out mate and personally, I reckon the Darche is superior.  The canvas feels more heavy duty than the OZtrail as does the zip.  Neither is fully waterproof but you could increase its protection by giving it a spray with something like the Nikwax Waterproofer..?  They'll both stand up against a bit of dust but because of the superior canvas used by Darche, theirs will hold up better.  If you're heading into the red centre though mate, I don't know that anything can resist that powdery stuff ;)  Hope that helps.  Cheers

G'day John, 

The Darche Outbound Swag Bags are canvas, so not really waterproof as such. If you want a bag that will offer a much greater level of protection from the elements, I suggest you look at the Darch Nero Gear Bags, these are water, snow and dustproof and come in a range of sizes to fit swags or other gear.

G'day Ben,

Unfortunately, we don't have the Darche Ridgedome in stock at the moment so I can't physically check this, but according to the dimensions provided from Darche, you should have no issues fitting the swag and mattress. Additional bedding may make things a little more snug though.
