Previously, the 5 degree nights were in the HH, and then I did feel cool until I used the VB.
So, I think I may just be, as you say, a very warm sleeper. I normally have my feet out of bed at home and the window open all year round. It just may be this is a heat problem not a condensation problem.
I'm wondering, if I use a breathable underquilt, would I be better going for synthetic so it will keep its loft even if I do sweat, or will I not have the problem because the UQ is breathable? Thanks for the tips on which brands to look for too. An UQ is something I hadn't considered because I was happy with the HH SS, but I may have to consider a UQ for the Black Bird, which I'm finding I enjoy more than the Explorer.
Well, if you are going to sweat into an UQ- if you can't find a way to regulate your body temp so that your body does not try to cool you off with sweat- well, I'd rather sweat into Climashield or Polarguard than into down. Though again, at least the VB will keep the moisture out of whatever UQ you choose. Your back might be wet, but at least your down/CS won't. OTOH, many of these quilts are quite vent-able, or adjustable, to allow a good bit of air to circulate under you when needed. So, maybe if your quilt is not TOO warm to start with, plus hanging it looser as needed, maybe you could achieve dryness. Anybodies guess.
I've always meant to attempt setting the SS up on the BB ( I have the LONGER Explorer model SS). But the trouble with the SS, even without the space blanket/VB, is the outer shell ( UC ) is still a VB. So if you are too hot to use the space blanket on top of the OCF HH pad, things might still get soaked from condensation against the cold outer shell/UC.
I'm going away again in a week or so, so will try without the VB to see if that makes a difference.
BillyBob, thanks for taking the time to give me such comprehensive answers to my questions.
You are very welcome. I hope the answers are correct and somehow helpful. Good luck on your next attempt!
