A knitted convolute protective sleeve is disclosed. The sleeve is knitted from filamentary members to form alternating crests and troughs lengthwise along the sleeve. The crests and troughs may be formed by alternatingly knitting segments from relatively stiff and relatively flexible filamentary members, by interlacing stiffening hoops at spaced intervals lengthwise along a knitted sleeve having a smaller nominal diameter than the hoops, or by varying the knitting parameters, such as loop density and loop length as a function of length along the sleeve.

Multilayer sleeves for insulating or protecting elongated substrates are disclosed. The sleeves are continuously knitted in different sections integrally joined end to end, the sections being formed of different filamentary members chosen for desired characteristics. The sleeves are formed into the multilayer configuration by reverse folding the sleeves inwardly to place one section coaxially within another. Sleeve ends may be finished with welts to prevent raveling and serve as a clinch on the elongated substrates. Rib knits are used to form insulating air pockets lengthwise along the sleeves to augment the insulating effectiveness.
