Unlike vinyl, or PVC fly lines, the clear, polyethylene coating on GSP Skyline does not contain the volatile chemicals that must be added to PVC in order to create a fly line. This shift in technology is important to maintain the durability of the line. Previously, these chemicals would constantly migrate into the environment. This is why we steer away from PVC baby toys and food containersthey emit poison. As those chemicals migrate out of the plastic, a void is created in the compound. Not only does this alter the compound from its initial characteristics, but that void forces the compound to crack over time. This is where the circumferential cracks on a PVC fly line are born. Add dirt, oil, and other foreign debris to the cracks and performance degrades. Monic lines do not lose material over time, and therefore do not crack. This is important in the overall durability of the line and its performance longevity for the angler.
GSP Skyline is made with a gel-spun polyethylene core and a specific blend of polyethylene polymers to create the clear coating. All of these materials begin lighter than water (Specific Gravity < 1.0). The buoyancy of this shooting line, combined with its natural tendency to repel water allows for long, effortless mends and easier pick ups so that you can keep the fly where you want it.
Made in the USA
Monic Fly Lines are made by the hands of a few dedicated individuals in Boulder, Colorado USA. The line, its core, the spools, the box, and even the ink and labeling are all made in the USA.
