The Ergodyne GloWear 8320Z is an ANSI/ISEA 107 Type R, Class 3 mesh hi-vis safety vest with a zipper front closure, delivering the highest Class 3 coverage in a breathable, lightweight mesh design for hot-weather and high-exertion traffic-zone work where solid-fabric vests increase heat stress — the mesh version of the standard 8330Z Class 3 zipper vest.

Why the Ergodyne GloWear 8320Z brings mesh comfort to Class 3
Class 3 is mandatory in high-speed zones — but a worker who is overheating in a solid-fabric vest is the worker most likely to take it off, and that is a compliance failure where visibility is critical. The 8320Z answers that with an open-mesh fabric that lets air move through the vest body to cut heat buildup, a zipper front for secure retention, and the full Type R Class 3 coverage of 1,240 square inches. It is the mesh counterpart to the standard woven 8330Z. As Class 3 vests go, this is the breathable zipper pick, and the best hi-vis safety vests guide and ANSI 107 guide cover how to match a vest to the work zone. It keeps Class 3 crews cooler and on-compliance.
Safety first: the 8320Z is high-visibility apparel for being seen in traffic and low light — it is not protective clothing rated for a chemical splash hazard, cut, flame, or arc. For those hazards, wear the appropriate rated PPE, including chemical-resistant gear for chemicals. Keep the reflective striping unobstructed; Class 3 is for high-speed zones, so confirm it fits your zone with the when-do-you-need-hi-vis guide. Retire the vest once the fluorescent fabric fades or the tape cracks.
What the Ergodyne GloWear 8320Z listing documents
From the published specs: ANSI/ISEA 107 Type R, Class 3 certification; an open-mesh fabric body for air circulation; a zipper front closure for secure retention; and the same Class 3 compliance as the standard woven 8330Z (1,240 square inches combined). These are true class 3 mesh vest credentials and a genuine zipper hi-vis vest — a breathable class 3 vest for hot-weather high-speed work.
How the Ergodyne GloWear 8320Z compares to other hi-vis
For the hook-and-loop version of this Class 3 mesh vest, the GloWear 8310HL; for the standard woven Class 3 zipper vest, the GloWear 8330Z; for a Class 3 surveyor vest, the GloWear 8346Z; for a zippered surveyor-style Class 3 vest, the Ergodyne two-tone Class 3 surveyor vest; and for a Class 2 mesh zipper vest, the GloWear 8210Z. The complete hi-vis apparel guide covers the range.
Choosing the right hi-vis garment
Match Type, Class, fabric, and closure to the work zone, speed, and season. For garment families, browse the high-visibility, safety vests, and Class 2 vests collections; for shirts and layers, the hi-vis shirts, hi-vis jackets, and hi-vis hoodies; and for the class decision, the hi-vis shirts guide.
Where it fits by job and crew orders
The 8320Z suits highway, DOT, and utility crews in high-speed zones who want the highest visibility class with mesh breathability and zipper security through hot shifts. Size it correctly to keep the reflective geometry in place, confirm Class 3 for your zone, and retire it when the material fades; for outerwear options, compare the hi-vis jackets guide and the hi-vis rainwear collection. For crew orders, quantity purchasing runs through a free Amazon Business account — volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations, with the walkthrough linked in our footer.
Frequently asked questions
What is the Ergodyne GloWear 8320Z?
An ANSI/ISEA 107 Type R, Class 3 mesh hi-vis safety vest with a zipper front closure. It delivers the highest Class 3 coverage in a breathable mesh design and is the mesh version of the standard 8330Z Class 3 zipper vest.
What does Type R, Class 3 mean?
ANSI/ISEA 107 Type R covers roadway workers, and Class 3 is the maximum coverage class for high-speed traffic, requiring 1,240 square inches of combined background and retroreflective material, as the listing states.
Why choose mesh for Class 3?
Mesh's open fabric structure allows air circulation through the vest body, reducing heat buildup during high-temperature or high-activity work - the reason to select mesh over solid fabric when thermal comfort affects wearing compliance.
How does mesh support compliance?
Workers who are hot and uncomfortable in solid-fabric vests are more likely to remove them, creating visibility gaps in traffic zones where wearing is mandatory. Reducing the thermal burden helps keep the vest on.
How does it differ from the standard 8330Z?
Both are Type R Class 3 zipper vests; the 8320Z uses an open-mesh fabric for breathability, while the 8330Z uses standard woven fabric. Choose the 8320Z for hot-weather and high-exertion work.
How does it differ from the hook-and-loop 8310HL?
Both are Class 3 mesh vests; the 8320Z uses a zipper for secure retention, while the 8310HL uses hook-and-loop for quick access. Choose by closure preference.
Is this chemical or cut protective clothing?
No - the 8320Z is high-visibility apparel for being seen, not rated for a chemical splash hazard or cut protection. Use chemical-resistant or cut-rated PPE for those hazards.
When is Class 3 required?
Class 3 is required for high-speed traffic above 50 mph and complex or low-light work zones where Class 2 coverage is insufficient. Confirm the class with the ANSI 107 guidance and your traffic control plan.
Does it work day and night?
Yes - the fluorescent background provides daytime conspicuity and the retroreflective stripes return headlight and work-light beams at night.
What sizes are available?
Confirm the size and fit options on the product listing; a properly fitted vest keeps the reflective geometry positioned for its rated visibility.
How do I care for it?
Follow Ergodyne's care instructions and laundering limits; retire the vest when the fluorescent fabric fades or the retroreflective tape cracks, since faded material no longer meets its visibility rating.
How do I order for a crew?
Quantity purchasing runs through a free Amazon Business account - volume pricing, PO numbers at checkout, and tax-exempt eligibility for qualifying organizations. The bulk-ordering walkthrough is linked in our site footer.

Functionally, it works. However a little short and not big enough. I think the XXL and XXXL need to be separate sizes.
