Tropical Ivy Buckstrap. This 4th version of Poison Ivy features fluorescent orange and green strands, that makes this rope more visible in sun light. So, if you love the unique double braid construction and static qualities of Poison Ivy climbing rope, but always wanted an ultra-high visible rope consider that wish granted! Made in house with Rope Logic's 11.7mm Yale Tropical Ivy 24 strand rope. Grizzly splice buckstrap with aluminum snaps.
