>>1012806Maate I recommend bringing a hoochie pic related. You won't need to use it every night but it weighs fuck all and will save your butt when it rains. Ditch the poles you can just string it up on trees in the bush. Double up the cord and tie knots along it, so you can simply pull the cord around a branch and tuck one of the knots through a gap, or peg through any of the gaps takes like 2 minutes to put it up. If you have a sleep in just a bivvy in the rain your bag will get wet, your pack will get wet, your boots will get wet if you don't cuddle them. It's a shit time if it goes bad, but yeah you can get away with it on clear nights. You can collect rainwater off the hoochie which is handy, just tie a little bit of cord to it somewhere near a corner, tie a little stick on this then put it into your water bottle, get it to wedge up against the inside of the neck and your bottle will fill.
By the pic that set looks like the jungle bag and the regular one? The jungle bag is often not enough on a cold night, use the heavier bag. It's designed for the tropics where you end up stark naked sweating your ass off at midnight with no sleeping bag anyway. I've never had to double them up and I think my record was about -15c in tekapo. Goes without saying bring a mat? Or you'll be cold as shit. Don't zip your head up inside the thing they don't breathe that well, you might wake up in the middle of the night freaking out because you can't find the zipper to get some needed fresh air.
