Worked well for what it was. A super thin lightweight ground sheet for my Haven tent. Used it 4 nights in a row on all Types of terrain and it didn’t puncture.
Poly cro is amazing. I've been using it for the past two summers while hiking the continental divide trail through Colorado. I have spent at least 30 nights in my six moons design tent with Poly cro underneath it. This reduced the weight of my total tent package by 4 ounces versus using Tyvek. If you want to go light this is the way to go. As noted, it is a lot like using really tough saran wrap but it is really tough.
