Loc Sleeves have multi-purposes for locs. They are used mostly at night while you sleep to protect locs. Even with a satin pillowcase locs can lose its neatness and are better maintained with a loc sleeve worn during bedtime. The material is designed to keep locs intact during the duration of a loc maintenance. Locs should always be protected, even when you are driving to avoid lint locking in your locs. They are even fashionable enough to wear when locs are not intact and in need of a maintenance. They are so many different ways the loc sleeve can be worn and so many different colors and prints.
