Cabela's North Star Bivy

Good quality at a reasonable price. If you want a bivy-type shelter, but mostly prefer a full size tent, this could would be a good choice.

I bought this shelter as a lightweight, compact alternative to a full size tent. I found the shelter very easy to set up, and take down. It packs quickly and neatly.

The first time I used it the winds were gusting pretty good, but the bivy didn't move much and seemed like it could handle much more with no problem. It remains dry inside with rain, though the fly touches the screen at midpoint—not sure how to fix that unless underneath something you could attach a line to.

As to room well, being what it is there isn't much. One's self, a ground sheet and sleeping bag, pillow, and it's full.  

I guess the bottom line for me is I much prefer a full size tent, even for solo camping. A full size tent weighs just a wee bit more, and is just a bit bigger. But then you don't need to be a contortionist to change in the tent, more room for stuff etc. Getting soft in my old age; I can't fit my nice, comfy airbed in the bivy!  

As far as comparing to other bivys, I can't compare because this is the only one I've tried. It's well made, and aside from the fly touching the screen, everything was good, no complaints.
