Heated Vest
A heated vest puts warmth across the core, at the chest and upper back, without sleeves that restrict movement, which makes it the highest-volume heated product and the entry point for most cold-weather ranges. Heating elements are bonded into zones and run from a rechargeable battery carried in a pocket, so the wearer adds warmth under a jacket or over a base layer. It is bought for winter outdoor work, hunting, riding, and retail winter lines.
Buyers specify heating-zone layout and count, heating-element type, battery and power format, the number of temperature levels, shell fabric and fit, and branding.
