jh92 Posted February 6 Report Posted February 6 This morning I woke up to the top of my sleep system damp, is this the heat coming off the bag and meeting the cold air? Just wondering if something like this would stop it: https://thetackletavern.co.uk/product/nash-waterproof-bedchair-cover-camo/?attribute_type=Wide I don't think its from the bivvy itself, I always get condensation on the inside but doesn't make the sleep system damp if that makes sense lol. yonny 1 Quote
yonny Posted February 6 Report Posted February 6 (edited) It's probs light condensation on your bag from your breath, frosting overnight, meaning it's damp in the morning. A waterproof cover will help, it'll frost on that instead 👍 Good old winter fishing.... love it. Edited February 6 by yonny jh92 1 Quote

Expand What shelter you using does it have a twin skin or skull cap on it? apparently it was quite misty last night I also heard the wife scraping her car windscreen this morning so it must have been cold lol jh92 1 Quote

I'm a bit paranoid about it pulling through and ruining the sleep system lol.

salokcinnodrog Posted February 7 Report Posted February 7 I think it's condensation from your breath and the ground. I use an Ultimate Night Fleece Cover myself. I know that it's colder and you get more condensation not using a groundsheet, but even so I still often don't in winter on single overnighters jh92 1 Quote

Expand It's completely normal/natural, can't be stopped. A protective waterproof cover will help protect the system if you're worried. jh92 1 Quote

Yeah it was a bit frosty 🤣 Expand Single skins used to be notorious for condensation if you can get a skull cap or skin for it that will make a difference as the skeleton of the frame work will create an air gap to help. ( apparently, putting the unhooking mat on top can also help) most other umbrella type shelters with the spokes on the inside can’t create the air gap so the skull cap/ skin is pointless. a waterproof sleeping bag cover will help to stop the bag getting wet. jh92 and salokcinnodrog 2 Quote

I confess, I don't know if it is still available but here is a link: https://ultimateangling.com/en/fishing-sleeping-bags/ultimate-night-fleece-cover It may be an eBay search for unsold stock jh92 1 Quote

Carpbell3 Posted February 8 Report Posted February 8 Other than raise the temps in the bivvy above the outside temps you will always get condensation the ultimate bivvy set up is a pricey silent generator way over powered and a 500 watt heater once seen a guy with a halogen bulb heater the warm orange glow looked worth the 2k generator you need to run it.
