What's a good Bivy or 1 man Pack tent?

[Pace Maker]

I have an upcoming elk hunt in Montana scheduled for October, I was wondering what you'd recommend for a pack tent or bivy. It's a horseback pack in, but once in we'll be hunting on foot. We'll have outfitted wall tents to stay in but if we find some animals just before dark a few miles away I can't see hiking back to the main camp to sleep for a couple hours then hike back in the dark. Thanks for any advice.

I like those blue tarps from the hardware store, about $10.

I have the north star bivy from cabelas. Weighs next to nothing, easy to set up and inexpensive. Has a removable rain fly in case it gets too warm.
