I'm looking for a harness that can safely accommodate a 440-pound individual, likely around size 6X. It's crucial that the harness is rated for this weight to ensure maximum safety and reliability during use. Please provide details on available options, including material, comfort features, and any relevant certifications that demonstrate the harness meets required safety standards. Additionally, let me know about lead times and pricing. Thank you!
