ActionHeat 5V Heated Vest Liner – Rechargeable Core Warmth for Outdoors (S/M)

Feel-warmth that travels with you

The ActionHeat 5V Heated Vest Liner is a slim, rechargeable layer designed to be worn under a jacket or over a base layer. Its three built-in heating panels are positioned at the chest and upper back to deliver focused warmth where you feel it most as you move through cool mornings, breezy rides, or damp outdoor environments. This lightweight design adds minimal bulk, making it easy to layer your outfit as the day evolves.

Powered by a USB-compatible power bank, the vest uses infrared heat with a reflective design to distribute warmth efficiently. The soft interior (100% polyester) and durable nylon exterior offer a comfortable touch against the skin while standing up to outdoor use. When it’s time to refresh, it’s designed for easy care with a gentle-cycle wash, so you can keep wearing it on regular outdoor excursions.

Three heat levels, intuitive controls

Adjust warmth with a simple touch control that offers three heat settings. Four LED indicators provide a quick read on battery life, helping you plan activities from sunrise to sunset. The convenient zip-front design makes layering under or over other garments straightforward and secure.
