ANTI-SLIP TECHNOLOGY: Anti-slip silicone printing holds you and the rowing cushion firmly in place to stay in place no matter how hard or fast you're rowing. THICK, BUT NOT TOO THICK: Avid rowers know that more than an inch of cushion is too much and changes your rowing motion. This cushion has been tested and tweaked to find the ideal thickness to add support without sacrificing form.
