I love my Gogo!!! Probably spent more nights out in it last year than all my other shelters combined.

I don't know what level condensation has to reach to become "dangerous" but I can assure you that you won't drown in a Gogo!!!

Will you experience condensation in this shelter? I can almost assure you of that. How much? Like anything else, it depends. I used mine in the Grand Canyon with just the netting and had almost none. I also used it buttoned up in the rain and I did experience moderate but completely acceptable (for me) levels of condensation. That's the price you pay for the simplicity and lightness of a single wall shelter. It was nothing I could not dispatch with the wipe of a bandana and remember that was under the worst conditions.

I have other W/B single wall shelters (Epic fabric BD One Shot and First Light, Goretex Military bivy, REI Minimalist Bivy)and the Gogo is no worse in the condensation department than any of them. And it's far better than a well ventilated but non-breathable shelter like my Lunar Solo.

The only scenario when I would not want this bivy/tent because of its condensation issues would be an extended trip in daily damp rainy weather when nothing has a chance to dry out. But I can also say that about any single wall shelter.

Go for it. It's a great shelter. Just don't play with your knife or your crampons inside or you may puncture the "pole" LOL!!!
