Work Jackets: Five Decisions That Fix the Spec and the Price

Work Jackets: Five Decisions That Fix the Spec and the Price

A work jacket quotation arrives as one number and a photograph of the work jacket. Neither tells you how it was built. That's not enough to compare two offers, because the number hides five decisions that set both the price and the service life. Put those five on the work jacket spec sheet and quotes become comparable line by line.

They are: shell fabric and weight, seam and trim build, hood and collar system, fit allowance, and the standard claim printed on the work jacket label.

How Work Jacket Weight Predicts Service Life

Work jacket GSM is the first number in every enquiry we get, and the least reliable one on its own. Two work jackets at 260 g/m² can differ by a third in wear life: weight tells you how much fibre is in the cloth, not how that fibre is arranged.

A 3/1 twill work jacket in 65/35 poly-cotton at 240–280 g/m² is the default for general site work: it resists pilling, holds colour through industrial washing, and dries faster than cotton. Cotton canvas at 320–380 g/m² takes abrasion better and feels heavier across the shoulder, but it holds water and needs roughly twice as long to dry overnight. A bonded softshell work jacket at 300–340 g/m² moves with the body and blocks wind, and it's the build that scuffs first at the cuff and hem because the face is a fine knit. The canvas vs ripstop comparison is worth reading before you pick a woven work jacket shell.

So ask for weave and yarn count alongside the weight, plus a Martindale result to EN ISO 12947-2 if the work jacket will be worn against concrete or steel. Weight is a starting filter, not the whole decision.

Where a Work Jacket Fails First: Seams and Trims

Warranty claims on a work jacket are rarely fabric failures. They're the pocket bag, the zip, or the seam that took the load.

Name the seam type in the tech pack: twin-needle lockstitch (stitch class 301) on main seams, flat-felled or bound inside if the work jacket is worn against skin in summer. Bar-tacks at pocket mouths and the base of the placket — four per pocket, not two. Pocket bags in poly-cotton rather than mesh, because mesh bags tear at the corner within a season of carrying tools.

A #5 nylon coil suits a work jacket. A #8 metal zip is stronger and heavier, and it's wrong on any work jacket that also carries an arc or antistatic claim, where exposed metal has to be covered or capacitance-tested. Below −10 °C moulded plastic zips go brittle, so ask for the temperature range on cold-store work.

If the work jacket must be waterproof, specify taped seams at 13–20 mm and accept that DWR is maintenance. A new work jacket that beads water is showing DWR, not a membrane. Once it wets out the membrane still blocks water but the jacket stops breathing — a re-proof, not a warranty claim.

Which Standard Claim Belongs on a Work Jacket

Every PPE jacket sold in the EU carries ISO 13688: general requirements for ergonomics, innocuousness, size designation, ageing and marking. A base for a claim, never a substitute: a work jacket marked ISO 13688 and nothing else has never had a protective performance test.

Pick the standard a work jacket must meet from the hazard, not the catalogue.

• Wet weather: EN 343, with the X and Y levels stated on the work jacket label.

• Visibility: EN ISO 20471. Class 2 needs at least 0.50 m² of visible material, class 3 at least 0.80 m² — which is why a navy work jacket with two bright bands isn't class 2, however good the tape looks.

• Cold: EN 342 for insulated work jackets. The Icler figure describes insulation, not a temperature rating.

• Heat, flame, arc, static: separate standards again, and a work jacket holds several at once only when tested as a complete assembly.

One work jacket clause trips up tenders more than any other. Visible area is measured on the smallest size offered, so adding a size below the one that was tested puts the whole range outside its certificate. Under Regulation (EU) 2016/425 the notified body number and module belong on that certificate too.

Fit Allowance Decides Whether a Work Jacket Gets Worn

A work jacket is worn over something. If the pattern allows less than about 8 cm of chest ease over a base layer and a fleece, crews size up, the sleeves run long, and the work jacket lives in the van.

Write the allowance into the work jacket pattern instead: 8–12 cm chest ease over the mid-layer, sleeve length measured from centre-back neck rather than the shoulder seam, and a drop-tail hem of 3–5 cm so the back stays covered when someone bends.

Then sizes. Under EN 13402-3 a European size is a body measurement, not a letter, so "L" means different things in Hamburg and Houston. If you sell in both markets, order two work jacket size charts off one pattern and check the grading at the extremes — 3XL is where cheap grading shows first.

How We Check a Work Jacket Before Bulk

At Wuhan Kinglong Protective Products (Hubei) Co., Ltd., work jackets run on the same 3-million-garment-a-year lines as the rest of the range, under NEO SAFETY® and BIZLINK®. Every work jacket lot gets a 20 × 20 cm panel cut and weighed against nominal GSM at ±5%, a pull test on the main seam, and a wash to ISO 15797 before any performance claim is rechecked. The gold-seal work jacket sample leaves with the trims that will actually ship, not stand-ins. Bulk inspection runs to ISO 2859-1 at AQL 2.5, and the certificate set travels with the shipment.

Work Jacket Questions Buyers Ask

Is a softshell a work jacket?

It's a work jacket if it's built like one — bonded shell, work-grade trims, tested seams. Softshell is a construction, not a standard, and a fashion softshell with a moulded plastic zip won't last a month on site as a work jacket.

What GSM should a work jacket be?

A three-season work jacket sits at 240–280 g/m² in 65/35 twill, 320–380 g/m² in cotton canvas, 300–340 g/m² in bonded softshell. Below about 220 g/m² you're buying shirt weight, and the pockets on that work jacket will fail first.

Does a work jacket need to be waterproof?

Only if the job is wet. A shower-resistant work jacket with DWR covers most site work. A true waterproof claim (EN 343, X and Y stated) adds cost through taped seams and a membrane, and costs breathability unless the membrane is a proper laminate.

How many work jackets should a crew be issued?

Two work jackets per person for a year-round programme, so one is always in the wash. Heavy soiling or central laundering usually means three, and the second work jacket is cheaper than the downtime a soaked one causes.

Can one work jacket be hi-vis and waterproof at the same time?

Yes, but it has to be tested as one garment. Combining EN ISO 20471 with EN 343 means tape, membrane and seams are assessed together. Two compliant fabrics sewn into one work jacket prove nothing about the finished garment.
