The FIRSTGEAR Gen 4 Heated Jacket Liner delivers fast, efficient warmth for powersports riding and other cold-weather activities. Designed to fit close to the body, this lightweight liner uses moisture-wicking stretch fabric and flexible carbon heating panels to improve heat transfer while minimizing bulk. Seven strategically placed heat panels warm the chest, abdomen, arms, collar, and entire back, providing comprehensive coverage with a 106-watt output.
The form-fitting construction provides comfortable compression and includes action-back flex panels for unrestricted movement. A lightweight, non-coated shell supports breathability, while the fleece inner collar helps manage moisture and adds comfort. Soft carbon panels conform to the body for efficient heat distribution, allowing the liner to deliver and retain warmth with less insulation and power than bulkier garments.
Dual-zone heating allows compatibility with either a Single or Dual Heat-troller™ controller. The liner can connect to a DC power source or compatible battery pack, and integrated coaxial glove plugs are conveniently stored in zippered pockets when not in use. The windproof design is durable, extremely lightweight, and hand washable for practical everyday care. This Large FIRSTGEAR jacket liner is covered by a one-year manufacturer's warranty and is identified by part number FSG527460.
