Dyneema Fiber DPX Technology 12-Strand Single Braid
Control-DPX combines Dyneema fiber and Samson's patented DPX technology into a strong, lightweight line that is winch and cleat friendly, while being incredibly easy on the hands. DPX adds the grip and "soft-hand" feel of spun polyester to the lightweight strength of Dyneema fiber. The result is an easily spliced, 12-strand single braid that performs better on winches than other single braids, while retaining the great "feel" you want in a mainsheet or guy.
Easy to handle Easy to splice High strength Lightweight Low stretch Runs through blocks without kinking Solid grip on winch drums
Heavy on the technical side...
