Just do a visual comparison between the ENO Vulcan Hammock Underquilt @ Rei 174.95
and Hammocks Gears Incubator. just bought for 235.00. And remember Eno's Ember, who's basic design looked flawed, but it was put on the market. As yet they do not have a proven product comparable to other venders underquilts found on these forums.
IT looks more then 60 dollars cheaper, considering one is 950 down and one is synthetic.
It was quickly eliminated as a choice when deciding to get a underquilt.
