Outdoor Research Stargazer Bivy

> "[T]hanks to the external fly fastener and Derlin single-pole system, you'll have enough headspace to sit up inside the bivy." The stated dimensions are 82 in x 26 in x 20 in. If we assume that 82 is the length, that leaves us with 26 inches or 20 inches as the height and the other as the width. If we're charitable, we could accept a height of 26 inches (though shoulder width of 20 inches sounds sparse). I'm nearly 6 feet, so 70-ish inches. When I sit up, I bend at the waist, slightly less than halfway between my head and my toes ... say, somewhere between about 30 and 33 inches. I have no idea whom this bivy is marketed for where 26 inches is sufficient headspace to sit up comfortably. Or 20 inches, either way. Even the picture of the person sitting up seems to show their head and torso extending past the peak of the "Derlin" pole.
