Paulm that's interesting are you saying you have the snugpak sf with the zip and it's a bit tight because I too am not nor will ever be a racing snake which has been a problem in the past with trying to find a bivi bag that allows room for me and sleeping bag.
Sent from somewhere?
Yep, exactly that mate, pretty snug around the shoulders once you are in it with a bag as well. Shame, as otherwise the centre zip and very small pack size would make it a winner for me. Tend to keep it in the day sack now as an emergency backup when out and about and use the dutch army one with the tarp (if not hammocking).
... where is a good place for breathable waterproof fabric that doesn't cost the earth??
Did you completely close the bag to seal it up? If so then of course the condensation will be horrendous, aside from one very expensive version of goretex that is designed for it, no bivvi bag is going to be breathable enough for you to breathe into the bivvi bag.
Infact, that goes against rule 1 of bivving:
Rule 1: Don't breathe into the bivvi bag
Rule 2: Don't breahte into the bivvi bag. Technically the same as Rule 1, but so important it's worth mentioning twice...
I have a Borah Gear Cuben and Sil nylon bivi - with mesh net over the face. It's long and extra wide and will fit a full length pad, me and both a golite quilt and an extra down blanket. It's cosy and dry. borah is in the U.S. And it cost a bit though in a sale. It's so light about 6oz that I don't really notice it. I've used it with a shaped tarp tent (HMG) the Echo 2 and that's great. I did also buy that second hand which meant I got almost 300 quid off! Yep that much! But so so light. My knees thank me!
At the price though I could get over the lively colour scheme so went ahead and bought it. Most uncomfortable night's sleep I've ever had
