Tachyon features a tough durable UV- and abrasion-resistant polyester sheath over a unique "dual-core" of nylon surrounding polyolefin inner core strands. The result is a rope that has superior strand definition and a firm, round shape which improves friction hitch performance. Additionally, Tachyon has no sheath slippage so it performs exceptionally well in popular mechanical devices without the "bunching" or "bagging" in the cover experienced with other 11mm climbing ropes. Tachyon was designed to have a slightly larger diameter than other 24-carrier ropes. The 11.5mm diameter and firm, round cross section improve grip and reduce hand fatigue without the weight or bulk of ½" ropes.
