Please note that this is a regular specific womens snowboard. The Gnu Zoid has a directional asymmetrical shape. This means that it has a dedicated heel side, & with a directional shape, this means that you will need to select a regular or goofy specific shape. This is the Regular shape in 149cm. The Womens Zoid only comes in one size, the only variation is the goofy or regular option. Asymmetric directional boards are rare as no one has been bold enough to test the water, in steps GNU! Reverse camber between the feet with standard camber underfoot gives floaty feel with plenty of grip when paired with the magnetraction edges. A great directional all mountain board.
