I wanted to establish what I consider the lower limits of the SOL Escape Pro Bivvy.  I’m not talking about survival either, just how cold I could  manage without risking making myself sick.  After testing it down to 36 F I believe I found my limit.  Put it this way, I will not be trying it in anything colder than this unless I’m in a true survival situation.  On the plus side, I was surprised at just how warm I was able to stay on a very windy and cold night.  To read the rest of the update please click here (and scroll down).
