Outdoor Research Deluxe Bivy Sack:
The Deluxe Bivy is the dream of those who want to shave ounces from their load but really love the idea of having the extra space and comfort provided by an overhead pole. Compared to the Advanced Bivy, it utilizes one pole rather than two, is faster to set up, but does sacrifice a few of the ventilation options. The forward roof section can be pulled back so the no-see-um netting is completely uncovered and the storm flap can be snapped around the edges to hold the forward roof section in place even though the zipper is wide open for maximum ventilation. The Deluxe utilizes GORE-TEX® top, sides, and foot section, as well as the impervious Hydroseal-200® coated floor. There are also sleeping pad straps to keep your bivy from twisting in the night.
