Our versatile Shipyard neoprene gaming mat features a shipping yard on one side that has been perfectly designed for our containers and seascape on the reverse side.
Flipping it over to the seascape side for a naval game was a nice surprise, the neoprene has just enough cushion that my minis don't slide around. The shipping yard side fits the container pieces perfectly, which is exactly what I was hoping for.
The double-sided design is what sold me, and both sides look sharp on the table. The neoprene has just enough grip that my containers don't slide around during a game. Flipping it to the seascape side gives the whole setup a totally different feel.
