The Loc Soc is made of a Lycra (Knit) Fabric, is 15 inches long and fits very comfortably on the head of adults and most children. The LOC SOC has multiple purposes and is great as a simple cap for protecting locks from dust as well as the hazards inherent in the environment (great for construction workers). It is also the perfect night cap to keep all of the Locks together thus eliminating the likelihood of lint buildup and pulling on the Locks which causes stress and damage to them. Taking showers have never been easier with the loc soc and it can even be used creatively to give a touch of fashion to your outfit. You can't go wrong with this hair accessory...it makes for the perfect undercap for the headwraps (see our headwrap section)!!!
