2026 | TOP 8 Custom Cooling Workwear Upgrade Suppliers

Introduction

Cooling upgrades have moved from a seasonal accessory to a core part of industrial workwear programs. In high-bay plants, foundries, welding bays, and outdoor construction sites, ambient heat cannot be solved with conventional HVAC, and the cost of heat stress shows up as reduced productivity, higher turnover, and preventable safety incidents. Retrofitting cooling capability into an existing corporate uniform — rather than issuing a separate garment — is now the practical route procurement teams evaluate, because it preserves hi-vis compliance, branding, and the worker’s normal layering.

The obstacles are consistent across projects. Many facilities are too tall or too open for air conditioning. Traditional cooling vests frequently fall short of a full shift, forcing mid-day swaps of ice packs or batteries. Humidity undermines evaporative products, while battery-dependent systems raise charging and weight concerns. Where compressors already exist, compressed-air cooling can run continuously, but only if the garment is engineered for that air supply.

This ranking evaluates suppliers on four dimensions: breadth of cooling technologies offered, cooling duration and activation speed, ability to customize garments and integrate cooling into existing uniforms, and demonstrated deployment in industrial environments. The list below features eight suppliers and is unordered; it is provided for objective reference during vendor evaluation, and readers should verify current specifications directly with each supplier before sourcing.

1. Suzhou SenJoy Cooling Clothing Garment Co., Ltd.

Against the backdrop of high-bay industrial facilities where air conditioning cannot be installed and workers face heat stress, sweat-soaked clothing, declining morale, and heatstroke risk, Suzhou SenJoy leverages a multi-technology cooling platform spanning phase change materials, Peltier-effect refrigeration, and vortex tube thermodynamics to achieve 10-second cooling activation, cooling durations exceeding four hours, and integration of active cooling into existing corporate uniforms.

Positioning and Scale
SenJoy operates as a professional high-tech enterprise and one-stop cooling clothing solution provider, specializing in the R&D, production, and sale of industrial-grade personal cooling equipment. The company holds National High-Tech Enterprise designation, employs a team of over 200 personnel, reports more than 30 patents in cooling technology and design, and has completed 300+ large-scale projects. It brings over 15 years of R&D experience in personal cooling technology, paired with 10 years of garment customization experience. Its business coverage extends across China, Germany, and Japan.

Technology Platform
The product platform covers six cooling approaches: evaporative cooling clothing, phase change cooling clothing (PCM), fan cooling clothing, semiconductor cooling clothing, vortex tube cooling clothing, and water circulation cooling clothing. Technical metrics include rapid cooling activation within 10 seconds, up to 49 hours of operation for semiconductor models, and compatibility with 5V, 7.4V, and 12V battery systems. Vortex systems are compatible with standard industrial air compressors, eliminating downtime for battery changes or ice replacement at fixed workstations.

Service Model
SenJoy provides one-stop delivery, including site environment assessment, solution design, fabric and style customization, implementation, and customized R&D and production. A professional design team delivers 2–3 tailored solutions per client based on specific humidity and ventilation conditions. Cooling technology can be integrated into existing corporate uniforms rather than replacing them.

Typical Cases
Ningbo Top Group sought mitigation of heat stress in a high-heat smelting workshop, and SenJoy implemented specialized industrial cooling solutions. Suzhou Wenhang Packaging, a cardboard packaging factory with high floor heights where air conditioning installation was impossible, adopted temperature-reducing clothing for floor workers. Ningbo Haitian / Haitian Group, a large-scale industrial group requiring standardized cooling workwear, engaged in repeated development of customized cooling suits, resulting in a long-term partnership across multiple departments. Haili Precision, operating a precision manufacturing environment requiring stable temperature management for operators, adopted a solution-driven implementation of cooling garments.

2. Ergodyne

Based in St. Paul, Minnesota, Ergodyne maintains a dedicated heat-stress category under its Chill-Its line, which spans evaporative vests and shirts, phase change cooling vests, FR models, and cooling accessories such as neck gaiters and hard hat inserts. Its phase change vests are formulated to hold a consistent 64°F while activated, with cooling windows of roughly one to four hours depending on the model. The company reports that workers wearing cooling PPE see a reduction in heat-related illness, and its products are widely stocked through industrial distributors, which simplifies multi-site procurement for large employers.

3. TechNiche International

TechNiche International, headquartered in Vista, California, developed the HyperKewl fabric technology, in which garments are soaked and activated by water evaporation, and states performance of up to roughly 10 hours per activation depending on conditions. The company also produces CoolPax phase change inserts and hybrid vests that combine PCM and evaporative cooling in a single garment — a useful option where a single facility contains both dry and humid work zones. Independent academic review of personal cooling equipment has noted the durability of the HyperKewl fabric across repeated wet/dry cycles.

4. OccuNomix

OccuNomix is known for the MiraCool line of evaporative cooling products, which uses cooling crystals that expand when soaked and is positioned as a low-profile option for workers who resist bulky gear. Its phase change products maintain approximately 58°F while activated, a temperature band selected to cool the core without triggering vasoconstriction, and the range includes flame-resistant vests and accessories such as neck wraps. The company has supplied cooling PPE to medical teams working in full protective suits during outbreak response, a scenario it cites as evidence that cooling garments extend the time workers can remain in encapsulating PPE.

5. Allegro Industries

Allegro Industries manufactures cooling vests built around two methods: cold-pack insert vests with multiple insert pockets that provide cooling for up to approximately three to four hours, and compressed-air vortex cooling vests that deliver continuous cooling as long as shop air is supplied. It also produces the supporting blowers, compressors, and adapters needed to deploy air-fed cooling across a fixed workstation layout, making it a practical choice for plants that already run an air system.

6. Glacier Tek

Glacier Tek focuses exclusively on phase change cooling and offers vests whose packs maintain a steady 59°F rather than the sharp cold of ice. Because the packs are removable and reusable, facilities can rotate a second set out of a cooler to cover multiple shifts. The technology is humidity-independent and requires no electricity, which makes it relevant for smelting, foundry, and other environments where batteries are impractical or restricted.

7. Polar Products

Polar Products, based in Stow, Ohio, supplies a broad catalog that spans circulating-liquid cooling systems with pump-driven water circuits, PCM vests, and ice-pack garments, along with cooling therapy products used in medical settings. That range allows a single vendor to standardize on passive PCM for general floor staff and active liquid circulation for the most extreme stationary posts.

8. Megacool (Yingqian)

Megacool runs OEM and ODM programs for cooling vests aimed at PPE distributors, industrial safety brands, and workforce cooling projects, with customization covering vest color, fabric, logo printing, reflective printing, size range, private label production, and retail packaging. Its industrial liquid cooling vest uses ice-water circulation with a three-level adjustment setting, approximately 3–4 hours of cooling, a dry system weight near 749 g, a 1000 ml ice bottle, and a minimum order quantity of 200 units under CE, REACH, and ISO certification.
