Designed with system profile, this liner provides enhanced standoff distance between the wearer's skull and the interior ballistic shell, absorbing high-energy impacts and drastically reducing the risk of behind-helmet blunt trauma (BHBT) and traumatic brain injury (TBI). Utilizing D3O's patented dual-density cushioning technology, the Halo XL system exceeds U.S. Army ACH blunt impact specification AR\/PD 10-02 by 33%, keeping deceleration forces consistently below 100g across ambient and extreme temperature ranges.\u003c\/p\u003e\n\u003cp\u003eEngineered for maximum operational endurance, the pad layout delivers up to 25% weight savings compared to traditional competitive foam helmet suspension systems. This significant weight reduction mitigates head-load fatigue during long-duration reconnaissance, maritime, or airborne missions. Built-in passive cooling channels run through the core of the pad geometry, facilitating active air circulation to dissipate trapped body heat, evaporate moisture, and prevent thermal degradation of the impact materials under harsh environmental conditions.\u003c\/p\u003e\n\u003cp\u003eTo ensure total operational compatibility, the Halo liner features an integrated crown pad recess and multi-axis flex grooves, permitting seamless integration with tactical communications headbands and active hearing protection without creating pressure hotspots. Covered in durable, MILSPEC moisture-wicking anti-microbial fabric, the pads resist odor buildup and skin irritation over prolonged use. The system mounts quickly into standard hook-and-loop velcro helmet interiors, providing an essential protection upgrade for institutional fleet modernization.\u003c\/p\u003e\n\u003ch4\u003e\u003cb\u003eKey Benefits:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eMaximum Impact Protection:\u003c\/b\u003e 1.0-inch thickness profile maximizes energy absorption and standoff, exceeding AR\/PD 10-02 ACH specifications by 33% (under 100g average force).\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOptimized for XL Helmet Shells:\u003c\/b\u003e Specifically engineered to fit Extra-Large ballistic and non-ballistic helmet interiors without compromising shell retention or stability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003e25% Weight Reduction:\u003c\/b\u003e Significantly lighter than legacy pad systems, lowering overall head weight to reduce neck strain and operator exhaustion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eIntegrated Thermal Ventilation:\u003c\/b\u003e Internal passive ventilation channels allow constant airflow across the scalp, reducing sweat accumulation and heat stress in tropical or desert environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eComms Headset Recess:\u003c\/b\u003e Built-in crown recess accommodates tactical communications bands and hearing protection wire frames without head pinching.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMILSPEC Anti-Microbial Fabric:\u003c\/b\u003e Wrapped in military-grade, moisture-wicking textile that inhibits bacterial growth and maintains hygienic performance.\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHook-and-Loop Modular Mounting:\u003c\/b\u003e Directly attaches to existing velcro disk arrays in ACH, MICH, FAST, and high-cut tactical helmets for rapid field installation.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003e\u003cb\u003eSpecifications:\u003c\/b\u003e\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cb\u003eBrand:\u003c\/b\u003e HighCom Armor\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eModel:\u003c\/b\u003e D3O Halo Helmet Liner System\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eSystem Profile \/ Thickness:\u003c\/b\u003e 1.0\/.75 Inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eShell Sizing Fit: \u003c\/b\u003eBallistic \u0026amp; Tactical Helmet Shells\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eCompliance Standard:\u003c\/b\u003e Exceeds AR\/PD 10-02 ACH Blunt Impact Requirements (10 fps impact speed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eImpact Performance:\u003c\/b\u003e Keeps average acceleration forces under 100g across hot, cold, and ambient environmental conditions\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eMaterial Structure:\u003c\/b\u003e D3O Patented Impact Mitigation Polymer + High-Density Comfort Foam Layer\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOuter Fabric:\u003c\/b\u003e MILSPEC Moisture-Wicking Anti-Microbial Textile\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eThermal Management:\u003c\/b\u003e Passive Airflow Channeling Network\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eHeadset Compatibility:\u003c\/b\u003e Recessed Crown Section for Tactical Headset Headbands\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eApplication:\u003c\/b\u003e ACH, MICH, PASGT, CVC, and High-Cut Ballistic\/Tactical Helmets\u003c\/li\u003e\n\u003cli\u003e\n\u003cb\u003eOrigin:\u003c\/b\u003e Assembled in the USA\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HighCom","offers":[{"title":"Halo Liner XL 1.0″","offer_id":49112822218996,"sku":"HCA-Halo Liner XL 1.0\"","price":48.95,"currency_code":"USD","in_stock":true},{"title":"Halo Liner M\/L 1.0″","offer_id":49112822251764,"sku":"HCA-Halo Liner M\/L 1.0\"","price":56.95,"currency_code":"USD","in_stock":true},{"title":"Halo Liner XL .75″","offer_id":49112822284532,"sku":"HCA-Halo Liner XL .75\"","price":56.95,"currency_code":"USD","in_stock":true},{"title":"Halo Liner M\/L .75″","offer_id":49112822317300,"sku":"HCA-Halo Liner M\/L .75\"","price":56.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2304\/8155\/files\/D3O-Helmet-liner-1.webp?v=1786427178","url":"https:\/\/rescue-supply.com\/products\/highcom-armor-d3o-halo-helmet-liner-system-extended-coverage-blunt-impact-mitigation","provider":"Rescue Supply","version":"1.0","type":"link"}
