I recently made this half pyramid:
Door is open, but can be zipped closed.
I like my pyramid tent but it weighs too much, so I left half as is and converted the other half into a triangle.
So, one side is 9 feet long by 4 feet wide, the other side is a triangle that extends 4 feet the other direction.
The design height is 48 inches, but it stretches to maybe 50 inches, I use a 53 inch pole so there's a small gap all the way around. This is the smallest height that works for me. My pyramid is 60 inches which is unnecesarily high so it weighs more and gets blown around by the wind more.
Tarp is 14.6 ounces including the zipper lock bag. Pole is 0.44 inch Easton - 53 inches long - 3.8 ounces. It would be perfect to use a trekking pole instead. Stakes are 2.3 ounce Ti. 21 ounces total.
What I like about this is:
all sides close to ground for better wind resistance
I can open the door totally or partially for ventilation if it's not raining and windy - not totally immune to condensation but about as good as it gets. If there is condensation the walls are steep so it runs to ground and there's enough head room (barely) to avoid touching walls when I lie down.
there's a triangular covered area to put my stuff
enough headroom so I can sit up - this is good if it's raining - I can sit under cover, fiddle with stuff, cook,...
I have tried various A-frame tents, hoop tents,... but I don't like these because I have to contort myself to get in, rotate feet around with dirt from my boots falling onto the sleeping bag. With a pyramid or this half pyramid I just sit down with my dirty boots in the "porch area", take boots off, lay down.
I might re-do it in Cuben which would save about 6 ounces so that would make the tent 9 ounces and total weight 15 ounces. I think I'll use this silnylon version for a while.
A lot of people consider a zipper something to be avoided, but I don't see it.
The two diagonal ridges are cat cuts 2 inches deflection. I should have had cat cuts for the zipper.
This is similar to Lawson's tarp and MLD Trailstar, but I like that I can close door totally with zipper.
