This is 3mm neoprene, coated on each side with polyester. Blue on one side, red on the other side. It is pretty light weight if you are comparing its density to other 3mm neoprene (but not the lightest weight I have seen). Basically, this is a giant mousepad.
It's a great surface for playing board and card games on. The neoprene mat makes it easy to pick up cards and bits off your table. Of course, having a board game table is the ultimate gaming experience. But if you are looking for a way to up your experience in a more portable and budget friendly way (or maybe have a good option for a second table) then this can be a nice upgrade.
This material is rough cut. You will have to trim it to the exact size you want.
