Techflex is my standard outer sleeve option, its a 10mil braided nylon sleeve. The braid it self is not as tight as MDPC-X and really shows the inner sleeving to provide a nice two tone color combo. PT is braided from 10 mil polyethylene terephthalate (PET) monofilament yarns. The material has a wide operating temperature range, is resistant to chemical degradation, UV radiation, and abrasion
