Product description
The Alpinestars HT Heat Tech Underlayer is designed for riders who need dependable warmth during cold-weather journeys without sacrificing comfort or freedom of movement. This lightweight heated vest fits comfortably beneath a motorcycle jacket, creating an efficient insulating layer for commuting, touring and adventure riding.
Four strategically positioned heating panels across the chest, lower back and back of the neck provide even heat distribution to the body's key areas. Riders can quickly select one of three preset heat levels using the integrated LED control button, while the intelligent automatic control system continuously monitors body temperature and adjusts the heat output to maintain optimal comfort.
Bluetooth® connectivity allows full control through the Alpinestars Heat Tech App. Using your smartphone, you can switch the vest on or off, precisely adjust the desired temperature and manage all heating functions with ease.
The soft polyester stretch construction offers a close yet comfortable fit, while brushed mesh inner panels cover the Graphene heating elements for additional comfort. An asymmetrical front zipper minimizes bulk beneath riding gear, making the vest ideal for layering during long rides.
The HT Heat Tech Underlayer offers dual power options for maximum flexibility. It can operate using the included high-performance 12V lithium battery for complete freedom of movement or be connected directly to the motorcycle battery during extended rides. A dedicated battery pocket securely stores the power pack while riding.
With its extended rear coverage, reflective front and rear graphics and intelligent climate management, the Alpinestars HT Heat Tech Underlayer is an excellent solution for riders looking for reliable warmth and modern heating technology throughout the winter riding season.
