For down think decent tent and VBL in super wet/cold conditions.
Oh well.
Have you ever crawled out of a VBL at minus 20F?
Only an idiot would reccomend a VBL in conditions like Lanche described above.
Hey goober, never recommended a VBL in above freezing temps like Lanche described (may want to read more carefully if you're able). I said COLD, not +20*... that's not cold.
A VBL's forte is keeping body moisture out of the down layers during extended trips in sub zero temps, not above freezing temps in wet-cold. Yeah, I've used VBL's in -20F... that's what they're for.
What a maroon.
