I have a 3 season burrow on order, and I'm trying to think ahead. If I have to go to ground, would the burrow work inside a bivy bag, or would the loft compress too much? I thinking an eVent bivy bag, lightweight.
Also, if it's really cold, would it work with a burrow inside a bivy bag, and a Mount Washington 3 on top of it all?
The burrow is rated for 15 degrees, and the bivy bag should give me another 7 degrees, plus an MW3, what, another 10 degrees?
Or maybe both burrow and MW3 on top of bivy bag?
I have an Exped Downmat 9, so bottom insulation is not an issue here.
