Ergodyne 41707 Heated Vest 4XL Unisex Polyester

Product Description

The ERGODYNE 41707 is a heated vest designed for workers who need core warmth without restricting arm movement in cold-weather jobsite conditions. Built from polyester construction and sized at 4X-Large for a unisex fit, this vest uses an integrated heating system powered by a 7.2V Red Lithium battery, which is included. The zipper closure keeps the front sealed against wind and cold while allowing fast removal when moving between indoor and outdoor environments. Five onboard pockets provide storage for tools, a phone, or spare gloves. Licensed tradespeople and general contractors working outdoor jobsites in fall and winter conditions are the primary users.

This vest is suited for use on commercial and residential construction sites, utility worksites, and any outdoor trade application where sustained cold exposure affects worker performance. The heated core design targets the torso, which supports overall body temperature regulation during extended periods of low activity such as inspection work, planning, or staged installation tasks. The unisex sizing and zipper front make it practical for a wide range of workers across trades including electrical, plumbing, HVAC, and general construction.
