Thermal-E Caps meet all applicable requirements for a Type I (top impact) helmet as outlined in ANSI/ISEA Z89.1-2009 (Class E) and CSA Z94.1-2005 (Class E). These caps also meet the ANSI/ISEA Z89.1-2009 voluntary standard for low temperature [LT] and reverse donning. Look for the official reverse donning logo to determine if your hard hat can be worn backwards without voiding approvals.
