>>1780213>The night I was out was a dry one>when the chance of dew is minimised Not really a thing in the uk. If you are out in the open and sleeping on grass there will be some moisture in the air, and if you are in a bivi then this will end up in some dampness in your bag. You really need to pick you campsites carefully and choose places that will give you some sort of a microclimate. ie under the cover of trees, not on grass, or somewhere that will definetly get a good breeze.
This is a good site to read about bivis on
https://www.thehikinglife.com/2018/11/the-essential-guide-to-ultralight-bivy-sacks/The pic in my first post was from CO in the states. In the UK I mostly use my bivi in the woods around home. I like to cowboy camp when the forecast is good, like at the moment, we havn't had a lick of rain. But I would never take it to the lake district or wales.
This pic is from Jordan. I took the bivi there, with a small tarp, thinking the dry climate would be ideal for the bivi. However, it ended up not being great. The night temps drop pretty sharply and the open country and clear skies meant there was a fair bit of condensation. Once I got further south and didn't have trees to sleep under I would regularly get condensation in the bivi. So I learnt to only sleep in it when the wind was high and just use it as a ground sheet on calm nights.
