I've decided to purchase a 10×10 pyramid shelter for both summer and winter camping. Like many, I plan to have mesh sewn to the perimeter to keep bugs out. I'm also considering having a ~8-12 inch sod cloth sewn along side the bug netting for winter use. In the summer I would have ties added to hold the sod cloth up for ventilation.
I'm willing to take the ~5-6 ounce weight penalty if the sod cloth would make the shelter storm worthy in the winter (e.g. reducing spin drift, wind, etc)
Before I pull the trigger and pay for this custom modification I have a few questions:
1) I'm curious if anyone thinks this a either a bad or good idea? Would it reduce ventilation to much?
2) Do these sod cloths get tucked inside or outside of the shelter? I've seen both recommended on various heavier weight shelters. This obviously impacts if I have the cloth sewn inside our outside of the perimeter mesh.
To give you an idea of a tarp with a "sod cloth" / "snow skirt" looks like, check out the twin sisters from MSR:
