Thread: light weight bivi gear

Im on the continual journey of sheading gear, my 1 man tent is mostly left on the shelf now days. DD hamock set up was good in steep/wet country but the under insulation issue meant things started to get bulky and heavy. The light weight DD tarp is a winner so now I'm looing at how low can I go....

So I've been looking at bivi bags that can team up with the Tarp.... goretex seems good, but is as heavy as a hammock and are $$. Ultra light stuff looks good but is mega$$$.

Then I found these..... tyvek based products:
Sleeping Covers nice and lightweight and simple.

https://www.2gosystems.com/products/trifecta light weight and versitile with full lenght zips and tarp tie off points. Is also a lot longer. could possibly just use a thermo liner and bivi only with this down to 4deg c?

and these guys based out of Wellington?

What sleep systems to people use in the bush vs tops.

What tips or tricks to people have?
