G'day Jason,

Darche spare parts are managed directly by Darche, so if you need anything you'd contact them directly.
We're not 100% sure what that looks like for them with the Kozi tents, but you can ask them via their Contact Us page.

G'day Neil,

The tent is required to be set up with the rain fly at all times.  The 600mm waterhead rating on the tent inner is in relation to the side walls in the even of crazy weather where you may get rain splashing up under the fly, or along that exposed front wall.  The basic material on the tent and fly is the same, however, they have different waterproofing treatments, hence the difference in waterhead rating.
The flooring is the same as the Coleman Silver series, and Swagger, as well as some of Oztrails original fast frame series.  This type of woven PE flooring has been the primary tent flooring over the last 30 years, and will be the same as in classic dome-style tents that have been the staple in camping for some time.
I have a 40 year old canvas touring tent with the same flooring type if that gives you an idea on durability. Ultimately, if you look after your camping gear, you shouldn't have any issue with durability.

Sorry Neil, I missed that specific part of your question - no this isn't made with ripstop material.

G'day Andrew,

The Kozi Series Instant up tents havent been treated with any kind of light suppression coatings, so whilst they are made of a darker fabric, they wont block light like the Oztrail BlockOut or Coleman Northstar tents do.
In terms of comparison to the Oztrail BlockOut series, apart from the above info, they are on a similar level with the quality of manufacturing and materials.  The Oztrail series has the added feature of a built in lighting system to offset the darkness inside the tent.
Hope that helps.

G'day April,

There may be, but it's not something we've heard of, or are aware of.
You can get in touch with Darche directly if you'd like to provide feedback.  As they are the manufacturing brand, they'd be keen to hear further info from campers.

G'day Michael,

Yes, this tent comes with the 3 walls required to enclose the annex space.

Thanks for the tip Meg!

G'day Ali,

The Kozi series is very new to us & at this stage we haven't had a chance to play with all the gear!
We've got this on our list of things to cover with Videos, but at this stage, we can only really compare it to similar-sized instant-up tents from other brands.
I'm not sure if Easy would be the right word, but it's definitely doable, and I'm 100% sure that whilst the first few times might be a bit on the slow side, you'll work out your own habits and ways of doing things that makes it easier!
