G'day Mel, 

It's not, no - the inner and outer sleeping bag material is cotton, but not the insulation.
If its not a down fill bag, the insulation will be synthetic.
Cotton can work ok for summer weigh domestic quilts, but it isnt suitable for sleeping bags.
Unfortunately as an insulative material it's warmth to weight ratio isn't great, and there's limitations with compressibility.

G'day Anne,

Colours are so tricky to convey, especially when everyone's device display settings can be slightly different.
I would say the colour is more like the video, but its definitely not green - its 100% grey

G'day Den,

Majority of single-orientation sleeping bags will have a zip on the right-hand side, but because this particular sleeping bag doesn't have a hood it doesn't matter which side is facing up.
If you put the logo side towards the ground, you're ultimately flipping it over & having the zip on your left.
Hope that helps.

G'day Paul,

They sure can, the zippers on both Pilbara bags are the same, so you can zip together the 0c and -5c versions.

G'day Sharon,

The Pilbara should do the trick for your Kimberley trip, these bags are a really popular model, and they can be opened up as a quilt for warmer weather, or paired with a fleece liner for cooler weather. Our Snowys Rating is based on customer feedback, however, it is also worth having a read through the reviews as a few people have made reference to the temperatures they've used their bags in.

G'day Nick,

The Pilbara range of sleeping bags are coloured based on style, so the C0 is red, and the C-5 is blue as per the images :)

G'day Diane,

The Pilbara C0 Sleeping Bag is rated for a comfort temperature of 0'C so we can't give you any guarantee of how warm you'll be in temperatures below zero. There is some extra fleece in the foot to help with warmth, but if you have cold feet we'd recommend some nice warm socks.

G'day Kate,

The Coleman Pilbara C-5 Sleeping Bag has a removable inner lining that when removed, makes it basically the exact same bag as the C0 option. I reckon your best bet might be to go for the C-5, that way you get the best of both worlds. 

G'day Kate,

Not wrong at all, if you got a liner that was rated as adding 10 degrees to your Coleman Pilbara C0 Sleeping Bag, then it would go down to about -10° when using the liner. 

Sure can Tynelle. But rather than zipping together side by side with the zipper down the middle, they are laid one on top of the other and zipped up with the zipper around the perimeter.

G'day Dave,

Unfortunately, the Coleman Pilbara C0 Sleeping Bag doesn't come with alternative side zips. However, if you bought two and laid one on top of the other, you will be able to zip them together to form a double sleeping bag.

G'day Stephen, 

The Coleman Pilbara C0 Sleeping Bag has a recommended maximum head height of 210cm. Your height (6"4) is approx 195cm, so you should have plenty of room in this bag.
