This is a Lost Mayhem board from their "Stealth" line of boards.
5'8'x18 1/2x2 1/8
It's a small, thin shape, so probably best suited to a grom/teenager or an adult on the lighter-side that's pretty experienced.
It's has a GoPro mount up front, so if you need the mount during the rental just let me know and I'll have it ready.
Check out my other listings if you need to rent more than 1 board. I can provide straps too, to tie the boards to the roof.
