Cooling Vests

What Counts as a Non-ANSI Cooling Vest

A non-ANSI cooling vest is a reusable, water-activated garment built to lower your body temperature through evaporation. It skips the reflective tape and fluorescent shell required by ANSI/ISEA 107, which makes it a lighter, less expensive option for job sites where high-visibility compliance is not part of the picture.

You will find these vests doing the most good in warehouses, farm fields, mechanic bays, and any other setting where staying cool matters more than being seen from a distance.

How Evaporative Cooling Actually Works

Soak the vest, and its inner fabric panels absorb water like a sponge. As you move and generate body heat, that stored water slowly evaporates off the fabric, and the phase change from liquid to vapor pulls heat away from your skin in the process. It is the same principle your body uses when you sweat, just amplified by fabric designed to hold far more water than cotton ever could.

Both vests in this collection use PVA (polyvinyl alcohol) style cooling panels, the same material found in most evaporative work vests on the market. One tradeoff worth knowing before you buy: evaporation slows down in humid air, so these vests perform best in dry heat and lose some punch on muggy days. If you work somewhere hot and humid year-round, plan on re-soaking more often to keep the effect strong.

Non-ANSI vs ANSI Cooling Vests

If your crew works roadside, in construction zones, or anywhere ANSI visibility is required, the CV200 gives you both compliance and cooling in one garment. If visibility is not a factor, the 390-EZ100 covers more sizes at a lower price point.

Our Cooling Vest Lineup

PIP 390-EZ100 Non-ANSI Cooling Vest (view product) — $31.19 is the vest to reach for when fit and duration matter most. It runs from small through 3XL, activates in under two minutes, and can hold 5 to 10 hours of cooling on a single soak, dropping your perceived temperature 15 to 20 degrees below ambient. The quilted nylon outer shell and water-repellent nylon liner keep the wet cooling layer from soaking through to your clothes, and the V-neck zipper front adds ventilation you will notice on the worst days of summer.

Pyramex CV200 Class 2 Hi Vis Cooling Vest (view product) — $41.52 earns its spot here as the hybrid option. Its inner evaporative PVA panels cool for up to 8 hours, and it also carries full ANSI 107 Class 2 certification with 2" silver reflective tape front and back. The quilted polyester shell, adjustable waist band, and zipper front closure make it a practical pick for anyone who wants cooling and visibility compliance without buying two separate vests.

Who Reaches for a Non-ANSI Cooling Vest

Heat stress is not a minor inconvenience. Bureau of Labor Statistics data shows an average of roughly 40 U.S. worker deaths a year from environmental heat exposure, and OSHA has an active rulemaking underway for a federal heat injury and illness prevention standard. A cooling vest will not replace water, shade, and scheduled breaks, but it is a practical layer of protection alongside them.

Activating and Caring for Your Cooling Vest

• 1. Submerge the vest in cool water for 1 to 2 minutes. Cold water activates the cooling fabric faster and holds the effect longer than warm water.
• 2. Gently squeeze out the excess. Wringing too hard can stress the seams over time.
• 3. Put the vest on over a lightweight shirt so the damp panels sit against fabric, not bare skin, for all-day comfort.
• 4. Re-soak whenever the cooling effect fades, typically once the fabric feels mostly dry to the touch.
• 5. Rinse after each shift, skip the fabric softener, which can clog the cooling fibers, and let the vest air dry fully before storing it to avoid mildew.

Round Out Your Heat Stress Kit

Pair your vest with a cooling shade for your hard hat to protect your neck and ears from direct sun.

FAQs

1. What is a non-ANSI cooling vest?

A reusable, water-activated vest that cools the body through evaporation. It skips ANSI/ISEA 107 reflective compliance, which makes sense for job sites where high-visibility gear is not required.

2. How long does a cooling vest stay cool?

The PIP 390-EZ100 holds 5 to 10 hours per soak. The Pyramex CV200 holds up to 8 hours. Actual time depends on temperature, humidity, and how active you are.

3. Do these vests need batteries?

No. Both use water-activated evaporative fabric with no batteries, electricity, or refrigeration required.

4. Can I reuse the vest?

Yes. Re-soak in cool water whenever the cooling effect starts to fade, for the full life of the garment.

5. Does humidity affect how well these vests work?

Yes. Evaporative cooling works best in dry to moderate humidity. In muggy conditions, evaporation slows down, so you will likely need to re-soak more often.

6. Can I wear a cooling vest with other PPE?

In most cases, yes, as long as the vest does not interfere with required safety equipment. Check with your safety manager if you are layering it under other gear.

7. What is the difference between the two vests in this collection?

The PIP 390-EZ100 is a true non-ANSI vest built for fit range and cooling duration. The Pyramex CV200 adds ANSI/ISEA 107 Class 2 reflective compliance on top of the same evaporative cooling technology.

Stay Cool Through the Hardest Shifts of the Year

Heat does not care about your deadline, but the right gear can keep you working through it. Shop the PIP 390-EZ100 for all-day cooling across a full size range, or the Pyramex CV200 if your crew needs visibility compliance too. Outfitting a whole team?
