The Jon Renau O'solite 'capless' wig collection weighs up to 50% less than traditional wigs due to its lighter materials and machine-back cap constructions. The open cap construction has an open wefted top and back with a velvet front hairline/nape allowing increased comfort around the hairline. The open cap allows for superior ventilation to keep the scalp cool and achieves a natural lift and movement making them the lightest, most comfortable open cap wigs in the market.
