The FIRSTGEAR Gen4 Heated Pants Liner is designed to provide fast, efficient warmth while fitting comfortably beneath your riding gear or everyday outerwear. Its form-fitting construction helps transfer heat directly to the body without restricting movement, making it suitable for motorcycle riding, outdoor work, commuting, and other cold-weather activities. The liner uses breathable, waterproof stretch Gelanots fabric across the front to help block wind and manage moisture when worn beneath jeans or other porous pants. Its lightweight design packs easily into the included zippered pouch for convenient storage and transport.
The integrated carbon “soft heat” heating elements deliver 48 watts of flexible, even warmth across the thighs, knees, and upper seat area. Dual-zone heating allows compatibility with either a Single or Dual Heat-troller™ for customized temperature control. Efficient heat transfer helps reduce the need for bulky insulation while maintaining comfortable warmth beneath outer garments. A dedicated remote Heat-troller pocket keeps the controller accessible, while integrated sock plugs tuck into zippered pockets when not in use.
Built for dependable long-term use, the FIRSTGEAR FSG527475 features high-tech moisture-wicking stretch fabric with an antibacterial treatment to help minimize odors and manage perspiration. YKK zippers, durable wiring, and connectors rated to -40°F support reliable performance in demanding conditions. The liner is hand washable and includes a one-year manufacturer’s warranty. With its flexible fit, wind-blocking front panel, efficient heating system, and practical storage features, this XL heated pants liner provides a low-profile way to add warmth to your cold-weather riding setup.
