Very interesting topic!! I have a hybrid cuban tarp (half cuban, half silnylon) and will keep a watch on how it preforms in the rain. I've just made it and only camped a couple of times with it so far. My former tarp, a homemade, cat cut silnylon winter tarp had to be shook out and wiped down before rolling up and stowed away. Since my cuban tarp is half silnylon, I already knew I would still be wiping it down.
Something I'd found with my silnylon and the reason I wanted cuban, was that during the winter, I found water (rain or humidity or maybe it was condensation from me??) on the inside of my tarp. It would freeze!! I was hoping that the cuban doesn't do this. This is something I'll be looking out for with the cuban. Plus with my tarp being two different fabrics, I'll be able to see right away how each is preforming in the exact same situations.
I've had my cuban tarp up in heavy rain but because I didn't take it down when it was wet, I don't know if it was heavier?? I was able to leave it hanging until the next day and by then it was totally dry.
So for now, I'm in "test mode" with my cuban tarp. I can say that I've tested it enough to trust it on a camping trip away from home. I really don't think I'm gonna get wet while under it.
My emphasis in bold on the Nexus lining. Seems that I recall this type of construction a few other rare times over the years. If such a material were available to the average folks then maybe we could come up with something that would do away with condensation altogether.ToddTex fabric is made exclusively for Bibler Tents. Totally waterproof, windproof, and extremely breathable—ToddTex is the best PTFE laminated tent fabric available. By stretching a thin layer of PTFE film over super-light ripstop fabric, we create nine billion microscopic pores per square inch of material. Water droplets are 700 times larger than these pores and can’t get through—even under high pressure. The inner layer of ToddTex is made from a fuzzy Nexus® lining that wicks water as fast as a paper towel—dispersing moisture vapor across, then through, the PTFE barrier.
