John and Benjamin: Oops, I left out the obvious! I was referring to the Gatewood Cape by Six Moon Designs. It seems to me from the pictures on his website that the Wild Oasis is the same design as the Gatewood Cape, except the Gatewood is a poncho tarp, and the Wild Oasis is not--but includes bug netting.
Benjamin: Yes, I suppose fully enclosed is often used for floored tents; we will have to come up with another term for tarps in which all the panels come to the ground, i.e. no sides are exposed. This would include most teepee-inspired designs such as the Hex and Gatewood, and the GG Spinnshelter.
John: yes, the Spinnshelter is fully enclosed and lighter. However, it does not double as a cape, so the Gatewood Cape at 11oz is lighter if you are a poncho user. Also, though I have never used a Spinnshelter, it seems to me that having a center pole will shed wind and snow better than the Spinnshelter, with it's long, unsupported ridgeline. This has to be weighed against the fact that the Spinnshelter has a lower profile. But I can sit upright comfortably in the Gaewood, and I am 6'2". I'm not sure I could do that in the Spinnshelter.
I remember reading a review on this site that the fabric ripped on the Spinnshelter during a strong wind where the grosgrain attaches the front pole to the ridgeline.
Don't get me wrong, I think the Spinnshelter is a great shelter, and I've thought about purchasing it. I guess I became a convert to a center pole teepee design after purchasing the Hex 3. Also consider that Ryan Jordan and Alan Dixon use the Gatewood Cape, with its center pole design, as their foul-weather conditions poncho shelter, as reported in their recent article.
