Battery‑powered cooling vests, including the ClemaCore model, entered limited release in summer 2026, providing full‑shift active cooling without ice or work interruptions.
A new class of cooling gear entered the market in 2026, targeting laborers who work in extreme heat environments such as construction sites. The first commercial rollout occurred during the summer of 2026 and is being distributed to industrial crews operating in temperatures exceeding 120 °F (49 °C) [1]. The product line is available globally, with manufacturers and distributors promoting use across North America, Europe, and the Asia‑Pacific construction sectors [1].
The primary developer of the battery‑powered vest is Clema, whose ClemaCore vest is described as a solid‑state, battery‑powered cooling system worn under personal protective equipment [1]. Additional industry commentary comes from safety‑gear review sites WC Safety, Heatgear360, and Workwear Ranked, which have evaluated the vest alongside other cooling solutions for construction workers [1]. The technology replaces traditional ice packs, chilled towels, or fan‑based systems with an electrically powered cooling element that operates continuously for an entire work shift [1].
Technology Behind Battery‑Powered Cooling Vests
Clema’s cooling vest incorporates a solid‑state thermoelectric module that draws power from a rechargeable lithium‑ion battery pack [1]. The module creates a temperature differential that extracts heat from the wearer’s torso, maintaining a surface temperature below core body temperature for the duration of a typical eight‑hour shift [1]. Because the system does not rely on stored cold, it eliminates the need for ice resupply or periodic cooling breaks [1].
The vest’s battery capacity is rated for up to 10 hours of continuous operation under 120 °F ambient conditions, according to the manufacturer’s specifications [1]. Heatgear360 notes that the device’s active cooling performance remains stable across a range of humidity levels, a factor that often limits the effectiveness of passive cooling methods [1]. The design integrates with standard high‑visibility and flame‑resistant PPE, allowing workers to wear the vest beneath existing safety garments without compromising compliance [1].

Industry Adoption and Market Availability
Innovative Battery‑Powered Cooling Vests Launch for Construction Workers in 2026
WC Safety’s July 9 2026 guide lists the ClemaCore vest among the top four cooling solutions for construction crews, citing its full‑shift capability as a differentiator from lower‑cost options such as the Ergodyne Chill‑Its cooling towel, which starts at approximately $5 per unit [1]. Heatgear360’s 2026 review similarly ranks the battery‑powered vest ahead of ice‑vests that require periodic re‑freezing, emphasizing reduced logistical overhead for contractors [1].
Workwear Ranked’s March 29 2026 article highlights that heat‑related fatalities remain the leading weather‑related hazard in construction, with over 900 occupational heat deaths recorded between 2011 and 2023 by the U.S. Bureau of Labor Statistics [1]. The article connects the introduction of active cooling vests to ongoing efforts to mitigate this risk.

Manufacturers report that the initial limited release targets large‑scale contractors operating in the southwestern United States, the Gulf Coast, and international regions experiencing prolonged heat waves [1]. Pricing for the battery‑powered vest is positioned in the mid‑to‑high‑range segment, reflecting the integrated electronics and battery system, while still being marketed as a cost‑effective alternative to recurring ice‑pack purchases [1].
Immediate Impact on Laborers and Employers
The deployment of battery‑powered cooling vests is expected to reduce the incidence of heat‑related illnesses among construction workers by maintaining core body temperature within safe limits throughout the workday [1]. By eliminating the need for workers to leave the job site for cooling breaks, employers can sustain productivity levels that would otherwise decline during extreme heat events [1].
Employers adopting the technology report lower rates of heat‑stress related absenteeism and a measurable decrease in on‑site medical interventions for heat exhaustion [1]. The vest’s compatibility with existing PPE also simplifies integration into safety protocols, reducing training time and administrative burden [1].
Regulatory bodies, including OSHA, have referenced active cooling solutions as compliant engineering controls for heat exposure, suggesting that the new vests meet existing occupational safety standards [1]. Contractors purchasing the vests can document compliance with heat‑stress mitigation plans, potentially influencing insurance premiums and liability assessments [1].
