The Black Stallion AH5040-BK Split Cowhide Wrap-Around Helmet Bib is made to be sturdy and reliable on the job. The wrap around coverage blocks more sparks, heat, & UV rays while the extended front coverage provides extra protection and reduces chest glare. The stronger, durable leather makes for a longer lasting bib, while the AH2140's FR Cotton lighter weight. It quickly and easily attaches to most welding helmets by using the push-on clips that provide a secure hold on most welding helmets.
