I'm reaching out to inquire about a specific ballistic helmet. I'm interested in a medium-sized, tan version that provides fast-response capabilities and meets high safety standards. I would like to know more about its features, specifications, and any additional options available in terms of customization or upgrades. Additionally, I'm looking to order one unit for initial evaluation. Could you please provide pricing details, lead times for production, and shipping options? If you have any brochures or product information sheets, I would appreciate it if you could share those as well. Thanks in advance for your assistance!
