Bivy bag inside tent to protect against condensation
It seems like interior tent condensation is basically unavoidable in many circumstances, so I was wondering if anybody has tried using a bivy bag inside their tent to prevent moisture from getting onto their sleeping bag/quilt and dry overnight clothing ? Thanks!
EDIT:
Wow! So many insightful responses to my original question! A little about my circumstances:
6 ‘2 male, experienced hiker.
I live in and hike in the south Island of New Zealand, a notoriously wet environment with high ambient humidity.
Most of my hiking trips are planned around staying in Department of conservation Huts. Some trips, this isn’t an option .
I have a single wall tent and I saw listed on Facebook marketplace an inexpensive , secondhand , near new north face bivy sac , which gave me the idea of using it inside the tent to keep my down quilt and clothing dry. I thought this might be a relatively low cost solution to getting my quilt and clothing wet.
I understand the importance of site selection when camping but sometimes I have to pitch my tent in a sub-optimal site.
So my take away from the below comments:
1.Based on the experience of most (but not all) users a bivy sac will exacerbate the exact problem I’m trying to solve. Just like rain on your wedding day… 😆
I need to upgrade to a double walled tent and maximize ventilation (e.g. keep the doors open when not raining). It’s a pity the bivy sac is a non-starter because the AliExpress tyvek sac mentioned below would have been the perfect solution.
Wipe down interior moisture with a cloth or sponge.
Experiment with covering my foot box with a rain jacket.
