FR Phase 1 Boxer Brief

The FR Phase 1 Boxer Brief from XGO delivers flame-resistant protection engineered for tactical professionals, first responders, military personnel, and workers in high-risk environments. These boxer briefs address the critical need for reliable FR base layers that provide both safety and comfort during extended wear in demanding conditions. Built to meet rigorous federal safety standards, the FR Phase 1 Boxer Brief serves as essential personal protective equipment for anyone working near open flame, welding operations, or explosive hazards.

Constructed from a specialized blend of Modacrylic and FR Rayon, these boxer briefs meet ASTM D6413 flame-resistance standards, meaning they will not melt or drip when exposed to direct flame—a critical safety feature that prevents secondary burn injuries. XGO's proprietary Superior Acclimate moisture-wicking technology actively transports perspiration away from skin to the outer layers, keeping wearers dry, comfortable, and focused on the task at hand. The intelligent fabric construction balances thermal protection with breathability, preventing heat stress during physically demanding work while maintaining the structural integrity required of true FR garments.

These boxer briefs are ideal for military personnel, law enforcement, firefighters, electricians, and industrial workers who require certified flame-resistant undergarments as part of their standard uniform or protective ensemble. The FR Phase 1 performs exceptionally well as a layering base under tactical gear, structural firefighting ensembles, or military combat uniforms, where moisture management and thermal protection directly impact mission effectiveness and wearer safety. Sizing information ensures proper fit across a range of body types, making them a reliable choice for team-wide FR uniform compliance and individual daily-wear comfort in high-risk occupational settings.
