4 years old version of the KiloNewton 3.5 

5″ of foam; 54″ x 48″ landing zone - a beast!

Tasteful Burgundy. It's a great mat in great shape. No issues! Fair warning this thing is heavy (IMO), but with good reason! 

$250 or make an offer. Boston area preferred. NH, PVD, even NY would be OK...but shipping isn't feasible.
