Brunton HeatSync Vital Vest

Features

1. USB-Powered Heat-On-Demand — Runs off any Brunton 5V/2.1A USB power bank for true field-portable warmth without proprietary batteries.
2. Carbon Fiber Heating Elements — Far-infrared carbon fiber panels deliver even, efficient warmth directly to the chest and kidney zones.
3. Three Heat Settings — Low, medium, and high modes let you dial in output to match conditions, activity level, and battery runtime.
4. Max Output of 122°F (50°C) — High setting pushes core-warming heat into the body to maintain temperature in subfreezing weather.
5. Stretch Neoprene Construction — Ergonomic neoprene harness flexes with you and holds the heating panels tight against the torso for direct heat transfer.
6. One-Size-Fits-All Harness — Adjustable design fits a wide range of body types, so one vest can rotate through the family or hunting party.
7. Wear Under Any Jacket — Low-profile base-layer fit slips under shells, parkas, and hunting coats without bulk or restricted movement.
8. Built for Low-Movement Cold — Designed for treestands, ice fishing, glassing, sentry duty, and emergency warmth when you're stationary and losing core heat.
9. Single-Button Operation — Simple power button with heat-level selection means you can run it through gloves without fumbling.
10. Backed by Brunton U-Proof Warranty — Covered by Brunton's lifetime service and support program.
