The FIRSTGEAR Heated Jacket Liner Gen 4 delivers fast, efficient warmth for powersports riding and outdoor use. Designed to fit close to the body, the liner uses high-tech moisture-wicking fabric with stretch side and back panels to improve heat transfer while reducing bulk. Seven flexible carbon heating panels warm the chest, abdomen, arms, collar, and entire back, providing balanced coverage and a comfortable fit beneath riding gear. With a 106-watt output, this Medium liner is designed to connect to a compatible 12-volt DC power source or battery pack.
The lightweight, non-coated shell supports breathability and mobility, while the fleece inner collar helps manage moisture and adds comfort around the neck. Form-fitting stretch fabric provides gentle compression for efficient heat transfer, and action-back flex panels allow unrestricted movement while riding. The windproof construction adds protection in colder conditions without requiring excessive insulation or weight.
Dual-zone heating allows the liner to be used with either a Single or Dual Heat-Troller™ controller, giving you flexible control over warmth. Integrated coaxial glove plugs provide convenient power connections and store inside dedicated zippered pockets when not in use. The liner is durable, hand washable, and extremely lightweight for convenient seasonal use and storage. Covered by a one-year manufacturer's warranty, the FIRSTGEAR Heated Jacket Liner Gen 4 combines targeted heating, low bulk, and practical riding-focused functionality.
