To remove the chinstrap from a PASGT helmet, first locate the attachment points on either side of the helmet. Gently pull the chinstrap away from the helmet to release it from the clips or hooks. If the chinstrap is secured with a snap or buckle, carefully unfasten it. Once detached, you can fully remove the chinstrap from the helmet.
