Where are the vents located on this thing and how big are they? Looks pretty sweet, but has anyone ever used one?

To add to the other answer, using the dual zippers you can also crack the doorway a little at the top to further vent it out and still stay fairly protected. Of course, this is assuming you don't have to worry about bugs or critters.

There are two main vents on this bivy- a large mesh panel down at the foot of the bivy, and another vent right above the head of the bivy. The nice part is that they are both designed so that they can be open even if it is raining for good ventilation.
