Do Safety Vests Expire? When to Replace Hi-Vis Gear

Safety vests don't expire. ANSI/ISEA 107-2020 sets no expiration date and no maximum wash count, so a hi-vis vest is replaced when its condition says so, not when a calendar does.

That makes inspection the whole answer to when to replace a safety vest. Kiwi's instructions for its rated garments are short: inspect daily, compare the garment with a new one, and retire it when the fluorescent color is noticeably faded or the retroreflective tape is damaged. Kiwi rated garments are also tested to withstand a maximum of 25 cleaning cycles when properly maintained, which gives you a planning number to go with the visual check.

Do safety vests expire?

No. ANSI/ISEA 107, published by the International Safety Equipment Association, sets how much fluorescent background and retroreflective material a garment needs and how that material must perform. Conformance applies to the garment as manufactured. The standard puts no date on how long that lasts, because it depends almost entirely on how the garment is used.

Two vests from the same carton show why. One sits in its bag in a dark supply room for a year. The other spends that year on a highway crew, washed every week and tossed on a truck dashboard at lunch. Same label, very different garments. Inspect both before issuing them, and expect the second one to be done first.

When to replace a safety vest: the triggers

Any one of these is enough to pull a garment from service.

How to inspect hi-vis gear before each shift

Kiwi's instructions say to inspect daily and compare the garment with a new one. The comparison is the step most crews skip, and it's the one that catches fading, because fading happens a little at a time. Look at the same vest every morning and you won't see the change. Hold it next to a new one in daylight and you will.

So keep a reference. Set aside one new, unworn garment of each style you issue, leave it bagged and out of the light, and don't let it drift into service when the crew runs short. It is the cheapest inspection tool in the supply room.

The tape needs a different test. In a dim shop or after dark, hold a flashlight close to your eyes and aim it at the vest from across the room. Good tape lights up a bright silver-white. Sections that stay gray or look patchy are returning less light. It's a field check, not a lab measurement, and it catches problems a daylight look misses.

Printable hi-vis inspection checklist

• Fluorescent color matches the reference garment in daylight, with no faded patches on the shoulders or back.
• Reflective tape is intact: no cracks, peeling, curling edges, missing pieces or burn marks.
• Tape glows bright and even under a flashlight held at eye level.
• No holes, tears or cut-off sections in the fabric.
• No stains covering the fluorescent fabric or the tape.
• Front closes fully over the layers being worn today.
• Label is readable and shows the class the job calls for.
• Wash count or in-service date is logged and under 25 cleaning cycles.

How long does a safety vest last?

There's no fixed number of months, and any figure quoted without knowing your conditions is a guess. Washing frequency and sun exposure drive most of it. Abrasion does the rest.

The 25-cycle figure is the best planning tool you have. To put it in perspective (simple arithmetic, not a Kiwi service-life figure), a vest washed once a week reaches 25 washes in about six months. Sun and abrasion can retire it sooner, and inspection still has the final say. The count assumes proper care (cold water, no bleach, no ironing, no industrial laundering), all covered in our guide on how to wash a hi-vis safety vest. Hot washes and high dryer heat can wear a vest out well before the count.

Sunlight works on a vest whether it gets washed or not. Kiwi's instructions note that gradual loss of fluorescence and reflectivity is expected with outdoor exposure. Store garments clean and dry, away from direct sunlight and UV. A vest that spends its off-hours in a locker keeps its color longer than one living on the dash.

Replace it when the job changes, too

A vest can pass every inspection point and still be the wrong garment for the work.

• The class requirement went up. The MUTCD requires Class 2 or Class 3 apparel for workers inside a temporary traffic control zone on a public road, and its guidance says night flaggers should wear Class 3. A vest that was fine in the yard may not be fine on the shoulder. Our post on OSHA safety vest requirements sorts out who needs what, and the Class 3 collection has sleeved vests, shirts and jackets.
• Winter layers changed the fit. The front of a rated garment has to be fastened. A vest that closed over a T-shirt in August may not close over a coat in January, so check the size guide and size up for winter. Or make the outer layer the hi-vis layer: the 3-in-1 neon safety jacket is rated Class 3, so no vest is needed over it. (Its zip-in fleece liner worn alone is not a rated hi-vis garment.)
• Something is covering it. Kiwi's instructions say not to wear a garment with less visibility protection over a rated one. An unrated jacket zipped over a Class 2 vest turns the vest into an undershirt.
• The hazard changed. Every current Kiwi hi-vis product is marked not flame resistant. If the work now calls for flame resistant or arc-rated clothing, a standard hi-vis vest is the wrong garment, no matter its condition.

Use this as general guidance rather than legal advice. Your hazard assessment, site rules and contract specs set the requirement. Inspection keeps you inside it.

Frequently asked questions

Do hi-vis vests have an expiration date?

No. ANSI/ISEA 107 sets no expiration date, so you replace a vest based on its condition and the manufacturer's care and use instructions. Kiwi rated garments are tested to withstand a maximum of 25 cleaning cycles when properly maintained.

How many washes does a safety vest last?

It depends on the manufacturer's testing. Kiwi rated garments are tested to a maximum of 25 cleaning cycles when washed cold, without bleach, and never ironed, dry cleaned or industrially laundered. Harsher washing can wear a vest out sooner.

Can you repair the reflective tape on a safety vest?

Kiwi's instructions say to discontinue use when the retroreflective trim is damaged. A patched band is no longer the material the garment was tested with, and there's no way to confirm its performance in the field. Replace the vest.

Does sunlight fade hi-vis vests?

Yes. A gradual loss of fluorescence and reflectivity is expected with outdoor exposure. Store vests out of direct sunlight between shifts and compare them against a new garment regularly.

Who should inspect hi-vis vests, and how often?

Kiwi's instructions call for inspection every day before use, so the wearer is the natural first check. A supervisor or safety lead can add periodic checks against a new reference garment and pull anything that fails.

Restocking hi-vis for a crew

Replacement goes faster when the next batch is already set up. Request a quote for crew quantities by style and size. If your vests carry a company logo, Kiwi keeps the artwork and order specs on file, so a reorder through our custom logo program doesn't start from scratch.
