This is my first bivy and it works great for fast and light camping. Just make sure you don't fall off your sleeping pad, due to condensation on the floor, but it usually isn't a problem. Also if bugs are a concern you may want to consider the tripod, Mosquitoes can bite through the netting if it is close to your skin. All in all it is much better than dragging a tent along and works great in combination with a tarp. It also eliminates the need for super bulky cold weather bags in most conditions.
