I remember looking closely at the Three Wire Bivy when it came out, and your blog is making me reconsider. My hiking style is very similar to yours; I'm in a very rainy climate, and I prefer solo backpacking above treeline. I'd rather risk high winds and rain for the chance at a spectacular sunset/sunrise than to dip down below treeline and lose all views. Most of my trips are 1-2 nights. Unlike you, I never eat in my tent (black bear problems), so that's not a concern for me.
I am trying to decide whether to get this bivy or the Integral Designs eVent Overbag. The Overbag is 10oz lighter, and I can cinch down the opening to expose only my face, which should improve condensation issues vs. the Three Wire. If it begins to rain, I can simply turn the bivy on its side, or throw over my rain jacket. Or I could bring a small tarp and still be lighter than the Three Wire.
However, the Three Wire is simpler to set up than a bivy/tarp combo, and the Three Wire has built in netting. I'm a big fan of simplicity.
So my questions for you are as follows:
For a simple overnighter, do you find that you miss the ability to sit upright under a shelter? Do you miss an overheard shelter during the day that a small tarp could provide?
With the bag zipped open and the bug netting shut, is it reasonably comfortable? For example, if I wanted to take an afternoon nap in the shade and be protected under the bug netting, would I feel much of a breeze?
Lastly, if you remove the stakes, can you sit upright and still have the head area cover you? In other words, If I wanted to get out in the rain, could I first sit upright, then use the awning to help keep rain out as I exit?
Basically, I am trying to decide between the versatility of the Overbag + tarp / mosquito net vs. the simplicity and ease of setup of the Three WIre. I am hesitant to take the Three Wire and a tarp, because this would be heavier than my huge GoLite Hex 3 with bug netting.
One last question: with the Terra Nova Laser Competition as light as the Three Wire, I am curious why you have tried bivying again?
Thanks in advance.
