Bivi Bags – Ultralight Options
I have bought a tarp last year for some overnight and multi day adventures on the bike and also walking in the hills. I have kept my kit ultralight with a mix of titanium, carbon and other light weight materials collected over many years of climbing in the Alps. Looking at under 5 kg for all the kit, shelter, cooking and food etc (not water).
Don’t want to carry a full on bivi bag as it will push up the weight, so was thinking about a Adventure medical Thermolite– 2 Bivi bag – sub 200g and will also make my sleeping bag warmer.
The problem:
It is fully waterproof but NOT breathable.
Do you think that condensation will be a problem for my Down Sleeping Bag under a tarp as I will never be fully enclosed i.e. face inside/breathing in the bivi bag? So it will just be my body inside.
Other Bivi’s seem too heavy and overkill as the tarp will protect me from the rain (big coverage) and bivis like the Terra Nova Moonlight that are breathable and around 200g are too expensive ~ £80.
I do have a sub 100g bathtub floor I’ve made for nice when nice conditions prevail but looking for a bit more coverage.
Advice or any other options will be great.
