## Abstract

A protective textile sleeve for routing and protecting elongate members against impact and method of constructed thereof are provided. The sleeve includes a plurality of yarns interlaced with one another, with the interlaced yarns forming an elongate, circumferentially continuous, tubular wall extending lengthwise along a longitudinal axis between opposite open ends. At least some of the plurality of yarns include tubular yarn having a central cavity extending along the length of the tubular yarn, thereby providing an impact resistant, dual layered wall to the tubular yarn. The sleeve can be constructed in a weaving, braiding or knitting process, wherein the tubular yarn can be interlaced as a woven yarn, braided yarn, or knit yarn, and further, the tubular yarn can be interlaced as an inserted yarn.
