Functionality and durability, the 1633 has it all with hi-vis safety. CSA Z96-09 Class 3 when combined with a Class 2 jacket or vest. ANSI Class 1. EN 471 and EN 20471, Class 1.
This review is NOT about the item. I've been wearing Blaklader for the past 5 years & I know it's the best.
This is about WRK Wear Company. Their customer service is second to none. I had a couple of questions with my order (not big issues) & they were all over it with personal 'phone calls & emails. They really go over & above. Don't think twice about buying from this Company.....SERIOUSLY.
