Dear customers and friends：

SECURITE VEST DM618: a pro-grade take on the warm vest for real security work

I’ve handled my share of “tactical” apparel that looks the part but falls apart under drizzle, door checks, or long nights on perimeter. The SECURITE VEST DM618 from Dellee is different—built on rugged 300D Oxford with a PU coating, it leans into function first. To be honest, it’s more than a warm vest; it’s a duty-ready layer with visibility cues and the kind of pocketing that saves seconds when seconds matter. And yes, it keeps core warmth stable when you’re moving in cool, windy conditions.

What’s changing in the field

The security market is shifting toward hybrid layers—lighter than winter jackets, tougher than fashion vests. Teams want a warm vest that carries radios, ID, and gloves without sagging, plus reflective elements that pop at night without screaming “high-vis” in daylight. DM618’s black-and-white blocking hits that balance; reflective trims wake up under headlights and stadium lighting.

SECURITE VEST DM618: key specifications

Model	DM618 (SECURITE VEST)
Shell Fabric	300D Oxford + PU coating; abrasion-resistant
Color/Visibility	Black/White blocking with integrated reflective elements (24h visibility)
Weight	≈ 620 g (size L, real-world use may vary)
Water Resistance	PU finish; hydrostatic head ≈ 3,000 mm; AATCC 35 spray rating: 90–100
Breathability	≈ 3,000 g/m²/24h (lab spec; field performance depends on layering)
Reinforcements	Bar-tacked stress points; YKK zipper; utility pockets
Standards/Testing	ISO 12947 abrasion; ISO 13934-1 tensile; reflective trims tested against EN ISO 20471 requirements
Comfort Range	Cool to mild weather over base layer (≈ 0–15°C), wind-shedding shell aids core warmth
Sizes	S–4XL; custom labeling available

Manufacturing flow (how it’s made)

Materials: 300D Oxford selection, PU coating consistency checks, reflective tape batch verification.
Cut & stitch: CAD patterning, double-needle seams, bar-tacks on pocket corners, clean binding.
Finishing: Reflective placement validation, zipper pull force tests, thread trimming, press.
Testing: Abrasion (ISO 12947), tensile (ISO 13934-1), water spray (AATCC 35), reflective retroreflection sampling per EN ISO 20471.
Service life: ≈ 3–5 seasons in routine duty; heavy daily use may shorten to 2–3.
Industries: Private security, venue ops, transport hubs, facilities management, campus patrol.

Real-world use and feedback

In night patrols, stadium ingress lanes, and mall incident response, teams reported fewer snag points and better ID visibility. “Radio sits tight, zips don’t jam,” one supervisor told me. Many customers say the balance of protection and mobility beats heavier jackets, especially when a warm vest is all you need between fall and spring.

Vendor comparison (what you’re really choosing)

Vendor/Model	Fabric/Build	Reflective/Standard	Lead Time	Customization
Dellee SECURITE VEST DM618	300D Oxford + PU; bar-tacks; YKK	Reflective trims tested vs EN ISO 20471	≈ 20–30 days	Logos, patches, pocket map, sizing
Generic Vendor A	150D polyester; basic zipper	Unknown compliance	≈ 35–45 days	Limited printing
Budget Vendor B	Non-coated poly; fewer reinforcements	Reflective not documented	≈ 25–40 days	Minimal

Customization and sourcing

Options include heat-transfer or embroidered badges, language-specific “SECURITE” marks, MOLLE add-ons, and pocket re-layout. Origin: 14/F., Yisheng Building, No.68 West Heping Road, Shijiazhuang, China. Typical MOQs are reasonable for agencies; pilot runs are possible—I asked.

Quick case note

A multi-venue events firm shifted supervisors to DM618 during shoulder season. Result? Team reported 18% faster radio access (timed drills), fewer wet-through complaints in light rain, and better recognition by contractors at night—a small but measurable safety bump. It’s not magic, but it’s the kind of incremental gain a solid warm vest delivers.
