The Outdoor Research Advanced Bivy offers full-on weather protection and has a commodious design featuring a generous footprint for those who prefer a little more wiggle room.
Outdoor Research says:
The spacious Advanced Bivy can be used in place of a single-person tent. The largest of our bivy sacks, the Advanced Bivy provides the most space for thicker sleeping pads and loftier bags. The patented dual-pole system can be used to increase ventilation and interior space, or left behind when weight and pack space are critical.
GORE-TEX® Respiration Positive™ fabric allows warm, moist air to escape but blocks outside weather, minimizing condensation while providing supreme protection from the elements. A zippered vent at the base improves airflow on humid nights.

What makes the Outdoor Research's Advanced Bivy obviously stand out from others is it's hoops. While not necessary for use, the user can place two hoops easily into snap-attached joints: one hoop will keep the hood off your face, raising it 20″ from the ground, while the other gives the hood some structural rigidity, letting you leave it open to vent while still protecting you from above.
The Advanced Bivy also includes a removable no-see-sum mesh netting at the hood, and mesh vent in the footbox that can be unzipped to let air flow and prevent condensation. There are also guy-out and stake loops on the bivy.
At 1010g it's not the lightest bivy available, but for some people the extra features will be worth the extra weight.
