Stay warm mile after mile with the FIRSTGEAR Heated Jacket Liner Gen 4 in 2XL. Part of FIRSTGEAR's industry-leading lineup of 12V heated motorcycle gear, the Gen 4 Heated Jacket Liner represents the most advanced version of their flagship inner layer — built for larger riders who want consistent, controllable warmth without bulk.
Powered by your motorcycle's 12V electrical system, the Gen 4 Liner delivers even heat distribution across the chest, back, and sleeves through integrated heating elements. Pair with a FIRSTGEAR heat-troller controller to adjust temperature output from the handlebar without stopping. The streamlined profile fits cleanly under virtually any riding jacket without restricting movement or adding noticeable bulk.
Works with gloves, liner pants, and other 12V accessories in the FIRSTGEAR ecosystem for full-body heated gear coverage. An essential cold-weather upgrade for commuters, tourers, and riders who push through winter. Available in 2XL.
