The DMM Highball is an excellent thick, hinged bouldering pad with a great landing area.
DMM have used Ballistic Cordura on the base, 100d Cordura on the top and Plastel on the closure flaps. The heart of the mat is thick layer of open cell foam, sandwiched between two high density foam layers. This gives a good even distribution even when from falling on uneven or rocky ground. One of the best hinged pads available!
If you're looking to invest a bit of money in a very well made hinged pad then you won't go far wrong with the Highball. For the money this is the perfect sized bouldering mat - small enough to be used for circuit bouldering and yet big enough to cover a good area of ground when going for highball numbers.
