I used to use an expensive and heavy dedicated groundsheet to protect the bottom of my Zpacks Solplex tent. It weighed almost a kilogram and was far too large for my tent. So why the switch to the Polycryo?
Why use Polycryo?
A thermal window coating kit is made out of Polycryo material. It’s basically a really thin yet durable sheet of plastic. It’s tough, lightweight and durable, three properties that a bought dedicated groundsheet made out PU coated fabric is not. It’s a cheap solution for protecting the floor of your tent a DCF or silnylon tent floors, they don’t cheap! For me, protecting it with a barrier that’s going to last, not break the bank and make my expensive tents last longer is an obvious purchase.
How well does it work?
The Duck brand has lasted me over 600 miles over 2 years in total.I could’ve gotten even more use out of it but I cut my final piece for a fresh sheet for the Pacific Crest Trail. But that’s only 0.7mm thick. Over the last couple of years, it kept the floor of my Solplex clean and dry and never got a hole in. The only times I’d cut a new sheet would be when I’m about to start a mega long hike and wanted a fresh piece. You can easily wash it though and it dries within minutes. The Teso Moll brand is 1.5mm in thickness so it should last even longer at a very small gain in weight, however, I haven’t fully tested it yet. It is so much cheaper than the Duck brand at the time of writing this review.
What’s there not to like?
The only issue I have with Polycryo is that it’s not recyclable. It does make up for it in longevity and honestly, you’ll get well over 100 nights from one sheet if you take care of it and are selective about where you pitch your tent.
