Port Authority K455LS Rapid Dry Long Sleeve Polo | Wholesale

Port Authority K455LS | Rapid Dry Long Sleeve Polo | Wholesale Blank Long Sleeve Cotton/Poly Polo for Decoration, Corporate Uniforms & Active Workwear — Adult XS–4XL

The Port Authority K455LS Rapid Dry Long Sleeve Polo is the wholesale blank long sleeve cotton/poly polo built for corporate uniform programs, active workwear buyers, and decorators who need the natural comfort of a cotton-dominant blend combined with Port Authority's exclusive Rapid Dry moisture management technology in a long sleeve polo engineered to keep wearers cool and comfortable through active working environments. Constructed from 5.6-ounce 60/40 cotton/poly baby pique, the K455LS delivers the soft, breathable comfort of a cotton-dominant blend with the moisture management performance that active wearers demand — the unique baby pique knit construction wicks moisture away from the body to the shirt's surface where it quickly disperses and evaporates, keeping wearers dry and comfortable through extended active shifts. The double-needle stitching throughout provides the durability that high-frequency uniform programs require, and the flat knit collar and cuffs, 3-button placket with pearlized buttons, and side vents complete a polo construction engineered for professional appearance in active working environments. Available in 3 colors — Charcoal, Classic Navy, and Jet Black — across XS through 4XL, the K455LS provides the core corporate neutral color range needed for most uniform programs. For the short sleeve companion, the K455 Rapid Dry Polo is the coordinating style.

Fabric, Performance & Construction

The K455LS is built on a 5.6-ounce 60/40 cotton/poly baby pique — a cotton-dominant blend that delivers the soft, breathable comfort of cotton (60%) combined with the wrinkle resistance and moisture management support of polyester (40%) in a fine baby pique knit construction. The Rapid Dry moisture management technology is the K455LS's defining performance advantage — the unique baby pique knit construction wicks moisture away from the body to the shirt's surface where it quickly disperses and evaporates, providing active moisture management that keeps wearers cool and comfortable through active working environments and extended shifts without the fully synthetic feel of 100% polyester performance fabrics. The double-needle stitching throughout provides the structural durability that high-frequency uniform programs require, ensuring the K455LS maintains its shape and construction integrity through repeated laundering.

The flat knit collar and cuffs provide a structured, professional finish at the neckline and sleeve, and the 3-button placket with pearlized buttons provides a refined, coordinated finish. The side vents provide ease of movement for active wearers. The long sleeve construction makes the K455LS the preferred choice for corporate uniform programs in cooler climates, fall and winter seasons, and programs that require long sleeve coverage for dress code compliance or professional appearance standards. Buyers sourcing Port Authority long sleeve cotton/poly polos wholesale for corporate and active workwear programs will find the K455LS consistently available across all 3 colors in the full size run from XS through 4XL.

Decoration Compatibility — K455LS Embroidery & Screen Print

The Port Authority K455LS is fully compatible with both embroidery and screen printing. The 60/40 cotton/poly baby pique construction provides a stable, smooth base for left-chest embroidery, and the flat knit collar provides a structured neckline that holds its shape through the embroidery process. Screen printing on the K455LS is straightforward due to the cotton-dominant 60/40 blend — standard plastisol inks work well on the cotton-dominant construction without the dye migration concerns that affect 100% polyester performance fabrics. Embroidery shops and screen printers running bulk decoration long sleeve cotton/poly polos for corporate and active workwear programs will find the K455LS's baby pique surface provides consistent decoration quality across the full size run from XS through 4XL.

The K455LS's 3-color palette spans core corporate neutrals (Charcoal, Jet Black) and classic corporate navy (Classic Navy) — providing the essential neutral color range for most corporate brand color systems in a long sleeve cotton/poly polo. The K455LS coordinates directly with the K455 Rapid Dry Polo in matching colors, allowing programs to outfit teams in a consistent Rapid Dry polo style family across both short and long sleeve options.
