A hi vis rain suit is a matching waterproof jacket and trousers in high-visibility fabric, sold as a set. It gives head-to-boot rain protection, and because the jacket has sleeves and the trousers carry leg bands, the outfit can reach the highest visibility class. Choose a rain suit when crews work in rain for long periods or need Class 3; choose a rain jacket alone when rain is occasional and workers already wear hi vis trousers or other compliant clothing. For active work in long wet seasons, pick a breathable suit; for occasional or standing work, a PU-coated suit is lighter on the budget.
Rain Suit vs Rain Jacket Only
| Factor | Rain suit (jacket + trousers) | Rain jacket only |
|---|---|---|
| Protection | Full body, including legs and seat | Upper body; legs get wet |
| Visibility | Class 3 as an ensemble is common | Class 3 possible with sleeves; depends on jacket |
| Speed to put on | Slower | Fast |
| Heat build-up | Higher | Lower |
| Cost | Higher per worker | Lower |
| Best for | All-day rain work, ports, roadwork in wet seasons | Occasional showers, drivers, supervisors |
Coated vs Breathable Rain Suits
| Type | Strengths | Limits |
|---|---|---|
| PVC or PU coated polyester | Waterproof, economical, easy to wipe clean | Little breathability; condensation inside |
| PU/polyester stretch knit | Softer, more flexible, quieter | Moderate breathability |
| Breathable membrane laminate | Waterproof with vapour escape; comfortable for active work | Higher cost |
In Europe, rain protection is rated under EN 343, which grades water penetration resistance and breathability of the finished garment. Ask for both classes when comparing suits.
Visibility Classes for Rain Suits
- ANSI/ISEA 107-2020: the jacket is typically Class 3 on its own; the trousers are Class E. Together they are a Class 3 ensemble.
- EN ISO 20471: the jacket and trousers can be certified together as a Class 3 outfit even when each piece is rated lower on its own.
- Wet conditions: microprismatic tape keeps more brightness when wet than glass-bead tape, which matters most for night work in rain.
Features Worth Specifying
- Fully taped seams on jacket and trousers
- Hood that fits over a hard hat, or a hood that stows in the collar
- Storm flap over the front zip
- Vents under the arms or across the back
- Trouser leg zips and adjustable hems to fit over boots
- Elastic or bib-style trouser waist
- A carry bag so each suit stays together
From Our Factory Floor
We have made hi vis rainwear since 2004. On rain suits the most common sample issues are:
- Sizes sold as a set: many workers need a different size for jacket and trousers. We recommend ordering the pieces as separate size lines and packing them together, rather than fixed sets.
- Crotch seam leaks: the trouser crotch takes the most strain. We check seam tape adhesion there first.
- Hood over helmets: a hood sized for a bare head pulls the jacket back and lifts the hem. We test hoods with a hard hat on.
- Tape on PVC: reflective tape on PVC must be welded or heat-sealed, not sewn, to keep the suit waterproof.
FAQ
Is a hi vis rain suit Class 3?
The jacket and trousers together usually form a Class 3 ensemble. Check the labels and test reports for the exact suit.
Can I wear the trousers with a different jacket?
Yes, if the combination still meets the class you need.
How do I stop condensation inside?
Choose a breathable suit, open the vents, and wear wicking base layers rather than cotton.
