Thank you @Zapruda.
I'll PM you now, and you can message me back whenever suits you. Enjoy the bush.
@crollsurf Thanks for your input / concern. By way of explanation I have a Berghaus Fast Hike 45, and just 2 segments of the Z lite is ideal for the specific back water bladder compartment to substitute the back support it usually comes with - which is perforated and doesn't work effectively as a butt bad on wet grass or ground. There's a Youtube review of the backpack I have here and you'll understand better why I just want 2 segments of Z lite.
https://www.youtube.com/watch?v=t5rPpKea-D4 (around 11.30 seconds into video.) The measurements of the 50 cm width of the Z lite works perfect for the entire back panel and the thickness is right also to fit into that back water bladder compartment.
I have a NeoAir Xlite Large as my sleeping mat, for my lightweight set-up / multi-day hikes. (I also have a really luxury heavy Self-Inflating mat, a Sea to Summit Comfort Plus Self-Inflating, which is a whopping 1.2 kg and bulky but is as comfortable as my queen mattress at home, and I use it for where I'm doing a short hike-in and more camping than hiking kind of scenario. And carry it in in a bigger 65 litre Berghaus Wilderness pack which swallows that bulk easily.) So I don't need a full length Z lite. Unless maybe I was to start Winter hiking and wanted it under my NeoAir Xlite, for extra insulation and redundancy built-in also in case of a mat failure. But at this stage I only do 3 season hiking, in fact more like 2 season hiking. Pussy I know.
Best,
Emma
