I brought this for camping trips. I went for the smaller one and its about 50% bigger than I expected but thats my fault for not looking at the dimensions.
I wanted something big enough to use, small enough to pack and the tube it come in is quite big but by no means too but. It went into my backpack no problem and to be fair had it been the size I was expecting I think it would have been too fiddly to actually use.
I LOVE IT. Spending a night by a camp fire and a river drinking and relaxing playing chess (badly) was amazing. Its now part of my essential kit
Its well made, the mat actually sits flat and light as a feather.
My only tip would be to paint a red and white dot on the bishops heads as after a few jack n comes I kept mistaking it for a pawn
Would recommend in a heart beat.
