Dear customers and friends：

SECURITE SWEATER DM604: a field-tested knit built for real security work

If you’ve ever stood gate duty at 3 a.m., you already know why a proper mens knit sweater matters. The DM604 from Dellee—marketed as the SECURITE SWEATER—leans into a wool/acrylic blend that, frankly, gets the balance right: natural warmth, industrial toughness, and a clean, uniform-friendly silhouette. I’ve seen a lot of “tactical” knits over the years; this one avoids the gimmicks and keeps what pros actually use, like a low-profile arm pocket and authoritative colorways (black or high-vis red).

Industry trendlines (quick take)

Uniform knitwear is shifting toward blended fibers, recycled inputs, and repeatable lab performance. Procurement teams want consistent sizing, snag resistance, and wash durability over multiple seasons. To be honest, pure wool looks great but is high-maintenance; pure acrylic is durable but can feel plasticky. The 50% Wool / 50% Acrylic route that DM604 uses is, in fact, where many agencies are landing in 2025.

Process flow and QC

Materials are batched and shade-matched, then knitted, linked, and stabilized via pre-wash. Seams and rib cuffs are tension-checked; pocket panel is bartacked where stress occurs. Final lots undergo dimensional stability (ISO 6330), abrasion (ISO 12947), and visual inspection under D65 lighting. The factory address is listed as 14/F., Yisheng Building, No.68 West Heping Road, Shijiazhuang, China—worth noting for supply-chain documentation.

Where it earns its keep

Corporate and campus security—indoors all day, outdoors at shift change.
Law enforcement auxiliaries and transit police—layered under duty vests.
Event and stadium staff—choose Hi-Vis red for crowd direction.
Aviation ground ops and facility patrols—pocket fits small notebook/ID.

Many customers say the arm pocket is small but handy; the rib hem holds shape better than pure wool after repeated washes. It seems that comfort improves after the second wash—common with wool blends.

Vendor comparison (procurement snapshot)

Customization and logistics

Badges, epaulettes, and arm-patch placement are available on request; colorways are black and high-vis red by default. Lead times are typically 25–40 days depending on MOQs; to be honest, embroidery can add a week. Packaging is barcoded per carton with size ratio assortments for faster issue.

Mini case study

A regional mall operator reported cutting uniform replacements by ≈18% over two winters after switching to this mens knit sweater, citing fewer puckered hems and better abrasion tolerance at the cuffs. Another campus security team liked the mens knit sweater in red for visibility during fire drills—simple, but it worked.
