This new version of the Wingspan neoprene playmat is double-sided (original and Oceania). The original mats are important because most Wingspan expansions are designed with them as the foundation; the Oceania mat is typically used when you're playing with nectar.
Why switch to neoprene? Some players prefer neoprene because it's easier to remove cards from them. Each playmat is sold separately so you can buy exactly as many as you need (i.e., if you usually play Wingspan with 1 other person, you can buy 2).
