Omega translates to "the end". These Lines are our high quality line that uses advanced technology and aggressive tapers to perform at the level you desire. They have a welded loop on either end and transition from an olive green to yellow to help show how much line you have out. Great advanced taper to help compete against some of the high end lines in the market. The 2 tone color helps build accuracy in your casting as well as a greater visibility on the water.
