On a recent trip I took two groundsheets to try out - a Polycro and a Tyvek.

Polycro is lighter, but that is where its advantage ends. It is not as durable as Tyvek and it seems to attract moisture and dust a lot more.

The UL fanatics can keep ranting about Polycro, but I would rather use two Tyvek groundsheets in future.
