From the manufacturer

The new ECS Hybrid coverstock is Brunswick’s latest advancement in performance enhancing technology. ECS expands the soft segments of the polymer chain producing improved friction and wider sweet spot resulting in fewer adjustments. ECS technology generates a faster refresh rate and a longer performance life for the coverstock. Paired with the Nirvana Ultra Low RG core, the Ultimate Nirvana provides effortless length through the heads with extraordinary backend continuation on medium oily to oily lane conditions.
