Firefighter Pants
Poseidon Structural Firefighter Pants are engineered as a core component of structural turnout ensembles used in interior attack, overhaul, rapid intervention, and high-heat suppression environments. Constructed using an Aramid IIIA outer shell (200 gsm / 5.9 oz·yd²), a PTFE-laminated moisture barrier (110 gsm / 3.2 oz·yd²), and a multi-layer thermal liner (250 gsm / 7.3 oz·yd²), the pants provide thermal insulation, flame resistance, antistatic performance, and controlled breathability during high-intensity fireground operations.
Designed for structural firefighting rather than wildland use, they integrate with certified turnout jackets, boots, gloves, helmets, and SCBA systems to support municipal, industrial, and ARFF response teams.
The Poseidon Structural Firefighter Pants utilize a multi-layer construction aligned with the material and design principles referenced in NFPA 1971 for structural PPE. The outer shell is woven from an Aramid IIIA blend containing meta-aramid for flame resistance, para-aramid for mechanical durability, and antistatic fibers to control electrostatic discharge in combustion-gas-rich interiors. This shell maintains thermal stability with negligible shrinkage under elevated heat and abrasion typical of interior attack conditions.
Beneath the shell, a PTFE moisture barrier laminated to an aramid-spunlace substrate provides liquid penetration protection while maintaining controlled vapor transmission. This layer is engineered to resist hazardous fluids, steam, and firefighting foams, reducing heat stress during extended activities. The thermal liner combines meta-aramid, para-aramid spunlace, and a comfort-facing aramid/FR viscose blend. This liner is designed to deliver balanced Thermal Protective Performance (TPP 37–45 cal/cm² range depending on size) and Total Heat Loss (THL 260–290 W/m² typical), enabling thermal insulation without restricting mobility.
The pants incorporate reinforced knee assemblies using para-aramid or PBI-enhanced overlays, Nomex® thread stitching, articulated patterning, and high-strength seam construction. These elements maintain structural integrity under crawling, kneeling, and tool-handling loads. Adjustable suspenders stabilize weight distribution, and the waist construction accommodates SCBA harness geometry. Flame-resistant reflective trim enhances visibility under smoke or low-light conditions. All components are manufactured under ISO-certified processes, and while the garment is not an NFPA 1971-certified item, it is constructed according to the material, durability, thermal, and functional principles used for structural firefighter PPE.
