Best Sun Protecting, yet Cooling Gear for Construction Workers

Construction is a year-round profession, and one of the most challenging parts of the job is working through the heat and sun. Long hours outdoors expose crews to heat stress, sunburns, and other serious health risks that can slow work down, or worse, send people to the hospital.

 

Luckily, the right cooling gear and sun-protective clothing can help workers stay cooler, safer, and more comfortable on the job. This guide covers what heat stress is, why sun protection matters, the different types of gear out there, and the best practices for using it.

 

What Is Heat Stress and Why Sun Protection Matters

On a hot jobsite, the body is constantly working to keep itself cool. When heat builds faster than it can be released, workers face heat stress, which makes crews more likely to lose focus, make mistakes, or suffer other injuries. If not managed, heat stress can quickly escalate.

•  Heat exhaustion is usually the first sign. Symptoms include heavy sweating, weakness, dizziness, nausea, and a rapid pulse.

•  If exposure continues, it can progress to heatstroke, which is life-threatening. Once core temperature rises above 104 °F, workers may experience confusion, fainting, or even organ damage. According to the Environmental Protection Agency (EPA), an average of 34 deaths occur in the workplace every year from heat-related exposure.

The sun itself is another hazard. Ultraviolet (UV) rays burn skin, damage eyes, and cause long-term problems like skin cancer. In fact, the World Health Organization (WHO) reports that work-related sun exposure is responsible for about one out of every three non-melanoma skin cancer deaths.

Ultimately, sun protection matters because it keeps crews safe in the short term and healthy in the long run. Heat and UV exposure can cause injuries that sideline workers, cost employers time and money, and in the worst cases, take lives. 

That’s why OSHA’s General Duty Clause requires employers to provide a workplace free from recognized hazards, including heat and sun. Some states, like California, Oregon, and Washington, already have their own heat standards that mandate water, rest, shade, and training when temperatures climb.

Key Factors When Choosing Cooling and Sun Protection Gear

When selecting gear for crews, focus on six essentials:

•  UPF/UV rating: Look for tested UPF 30–50+ fabrics. UPF 50 blocks about 98% of UV rays.
•  Cooling technology: Evaporative gear works best in dry heat, phase-change materials (PCM) provide steady relief in humid conditions, and moisture-wicking fabrics and vents improve airflow.
•  Visibility and safety: Choose cooling gear that integrates hi-vis colors or reflective strips to maintain compliance.
•  Fit and weight: Gear should be lightweight, comfortable, and compatible with hard hats, harnesses, and other PPE.
•  Durability and maintenance: Fabrics must handle abrasion, sun exposure, and frequent washing.
•  Cost and availability: Balance budget and performance. Affordable gear that’s easy to source and replace is better for long-term crew safety and branding.

Types of Cooling and Sun-Protective Gear: What’s Out There

The right gear depends on climate, work intensity, and how long crews are exposed. Here’s a breakdown of the most common options:

Cooling Vests

Cooling vests are worn over a base layer to pull heat away from the body. Here are some of the most common types:

•  Evaporative vests use water-soaked fabric that cools as it dries. They’re lightweight and affordable, but less effective in humidity.
•  Phase change (PCM) vests contain inserts that hold a set temperature for 2–4 hours. They work well in hot, humid conditions but are more expensive and heavier.
•  Ice pack vests provide intense cooling but can feel heavy and require frequent swaps.

Cooling Sleeves and Sun Sleeves

These slip over your arms to block the sun and help wick away sweat. They’re cheap, lightweight, and good for jobs where your arms are in direct sunlight all day. Just keep in mind they won’t cool your core, and if they don’t fit right, they can feel tight and uncomfortable.

Hats and Hard Hat Accessories

If you’re already wearing a hard hat, hard hat cooling accessories like wide brims, neck shields, liners, and sweatbands can make a big difference. They give your head, face, and neck some shade without getting in the way of safety gear. They don’t cover your whole body, but they’re inexpensive and easy to throw on with your PPE.

Cooling Towels, Bandanas, and Neck Gaiters

Cooling towels, bandanas, and neck gaiters are portable, low-cost tools that give quick relief when the heat ramps up. You can dunk in water, toss around your neck, or use on breaks. Plus, they’re portable and affordable. The downside is they dry out fast and don’t last long before you have to re-soak them, so they’re better for short relief than all-day use. 

Sun Protection Clothing

Long-sleeve shirts, pants, and gloves with a UPF rating are built to keep the sun off your skin. Good ones are made from lightweight, breathable fabric, so they’re more comfortable than they look. They’ll still feel warmer than short sleeves, and after enough washes, the sun protection wears down. But for all-day outdoor work, they’re one of the most reliable options.

Extra Gear: Shade, Misters, and Fans

For bigger crews or hot jobsites, sometimes you need more than personal gear. Shade tents, misting stations, and big fans can cool down whole groups of workers during breaks. They cost more and take a little setup, but they give everyone a safe place to recover when the sun is brutal.

Best Practices for Using Cooling and Sun-Protective Gear On the Jobsite

Whether you’re a worker or a site supervisor, there are some best practices you should follow to make sure your cooling and sun-protective gear actually does its job.

When to Wear What

Don’t wait until you’re overheated to gear up. Put on cooling vests, long-sleeve UPF shirts, or sun sleeves at the start of the shift, especially once the sun’s high and the heat really kicks in. Save heavier setups like PCM or ice-pack vests for long days or when the work is nonstop in full sun.

Care and Maintenance

Gear only works if you take care of it. Wash sun-protective clothing in cold water, hang it to dry, and skip the bleach since it eats away at the fabric. Also, soak evaporative gear before every use, and keep PCM or ice packs frozen in a cooler until you need them. Store everything clean and dry so it lasts longer.

Combining PPE Layers

Wear your cooling gear under your required PPE, not over it. A vest should go under a harness, and hard hat liners should sit inside the suspension. Safety gear traps heat on its own, so layering the right way helps you stay cool without cutting corners on protection.

Hydration, Rest & Acclimatization

OSHA stresses three basics: water, rest, and shade. Sip water often, cool off in shaded or misted areas when you can, and don’t push new or returning workers too hard right away. It takes about a week or two for your body to get used to the heat. If the work schedule allows, knock out the heavy stuff earlier in the day before temps spike.

Training and Recognizing Heat Illness

Every worker should know the early signs of heat stress, such as headaches, cramps, dizziness, nausea, or unusual behavior. Supervisors should reinforce training regularly, and crews should use a buddy system to watch for each other. If someone shows signs of heatstroke, call it an emergency and get help immediately.

Cost vs. Benefit

Buying cooling and sun gear might seem like another expense, but the truth is that it saves money and keeps people working.

What It Costs

A cooling vest will run you about $40 to $200, depending on the type, and UPF shirts, sleeves, or hats usually cost $20 to $70 each. Add in some upkeep (washing clothes, recharging PCM or ice packs, and replacing worn-out gear), and that’s pretty much the investment. It’s not nothing, but it's worth the money compared to what heat illness can cost.

The Payoff

The returns are where the numbers really add up. Every case of heat illness avoided saves on medical bills, workers’ comp claims, lost workdays, and project delays. 

According to OSHA’s Safety Pays Program, the average cost of a single heat-related incident is $37,658 for direct costs (e.g., medical expenses and compensation) and $41,423 for indirect costs (e.g., lost productivity, retraining, and replacement labor). That’s nearly $80,000 for one preventable incident. 

 

Compare that to the relatively small price of outfitting a crew with cooling vests, UPF-rated clothing, and shaded break areas, and the return on investment becomes clear.

Intangible Benefits

Besides the monetary ROI, there are other benefits to keeping your crew cool and protected.

•  Keeping people around: When workers know the company’s got their back, they’re more likely to stick around instead of jumping to another job. That means less turnover and less time spent hiring and training replacements.
•  Reputation on the line: A company that puts safety first builds a name people can trust, whether it’s clients, inspectors, or the crews themselves.
•  Staying out of trouble: Good safety gear and practices help avoid OSHA fines, lawsuits, or other issues that come when corners get cut.
•  Morale and trust: When crews see their employer invest in their well-being, it builds respect. People work harder, look out for each other more, and take pride in their jobs.

Frequently Asked Questions

How long do cooling vests last on the job? 

Depends on the type. Evaporative vests usually keep you cool for two to four hours before you have to soak them again. PCM vests last about the same, but they hold a steady temperature regardless of humidity. Ice pack vests hit you with strong cooling, but only for an hour or two unless you’ve got extra packs ready. 

Is evaporative vs. PCM better in humid climates? 

Evaporative gear works best in dry heat, since it relies on water evaporation to cool you down. In high humidity, that process slows way down, so the cooling effect is weaker. In those conditions, PCM vests or ice-pack vests are more reliable because they don’t depend on evaporation. 

Can you wear cooling inserts under a hard hat safely? 

Yes, as long as the insert is designed for hard hat use. Cooling liners, sweatbands, and neck shades that are OSHA- or ANSI-compliant won’t interfere with the hat’s suspension system.

How often should sun-protective clothing be replaced? 

Most UPF shirts and gear keep their protection for about 30–40 washes. If the fabric gets thin, faded, or stretched, it’s time to swap it out. For heavy use, replacing it every season is a safe bet. 

What are OSHA’s requirements/guidelines on heat and protection gear? 

There’s no single federal heat rule yet, but OSHA’s General Duty Clause says employers have to protect workers from known dangers, including heat. That means water, rest breaks, shade, and the right gear. Some states, like California, Oregon, and Washington, already have their own rules with stricter requirements when temperatures climb.
