Port Authority K500LS Silk Touch Long Sleeve Polo | Wholesale Blank

Port Authority K500LS | Silk Touch Long Sleeve Polo | Adult Wholesale Blank for Year-Round Uniform Programs, Corporate Apparel & Decoration

The Port Authority K500LS Silk Touch Long Sleeve Polo takes the legendary Silk Touch fabric — a 5-ounce 65/35 poly/cotton pique that has been a uniform staple for decades — and extends it into a long sleeve silhouette built for year-round programs, cooler climates, and dress code environments that require full-arm coverage. The silky smooth pique knit resists wrinkles and shrinkage through repeated laundering, maintaining a professional appearance across the full lifecycle of a uniform program. Available in adult XS through 6XL across 8 colors, the K500LS offers one of the widest size runs in the long sleeve polo category — making it the right choice for organizations that need to outfit everyone from petite staff to extended sizes in a single consistent style. For the short sleeve version of this fabric, the Port Authority K500 Silk Touch Polo uses the same 65/35 poly/cotton pique in a classic short sleeve cut. For a 100% polyester PosiCharge long sleeve performance alternative, the K540LS Silk Touch Performance Long Sleeve Polo is the natural upgrade.

Fabric & Construction

The K500LS is built on the same 5-ounce 65/35 poly/cotton pique that has made the Silk Touch polo family one of the most trusted uniform blanks in the wholesale apparel industry. The polyester component delivers wrinkle resistance, shrink resistance, and easy-care durability through repeated laundering, while the cotton component contributes breathability and a soft, natural hand feel that wearers find comfortable through a full workday. The silky smooth pique texture gives the K500LS a polished, professional appearance that reads as premium in customer-facing and executive-level uniform applications.

The flat knit collar and cuffs maintain their shape wash after wash without curling or distorting — a critical detail for long sleeve uniform programs where the cuffs are highly visible and need to maintain a consistent, professional appearance. The 3-button placket with metal buttons and dyed-to-match plastic rims provides a coordinated, polished look, and double-needle armhole seams and hem add durability at the stress points most likely to fail in active wear. Side vents improve freedom of movement and comfort during active tasks. The extended size run from XS through 6XL is one of the widest available in the long sleeve polo category, ensuring the K500LS can outfit entire organizations without requiring supplemental styles for larger sizes. Buyers sourcing Port Authority long sleeve polos wholesale will find the K500LS consistently available across all 8 colors in the full adult size run.

Decoration Compatibility — K500LS Embroidery & Heat Transfer

The Port Authority K500LS accepts all major decoration methods used in the wholesale apparel industry. The 65/35 poly/cotton pique surface is fully compatible with embroidery, heat transfer, and direct-to-film transfers. The flat knit collar provides a stable base for embroidery near the placket without puckering, and the long sleeve construction creates additional decoration real estate on the sleeve for team numbers, individual names, or secondary logo placement.

Screen printers working with the K500LS should use polyester-compatible inks or low-cure systems to prevent dye migration on the polyester component of the 65/35 blend. For heat transfer and DTF programs, the smooth pique surface provides good adhesion and color vibrancy. The K500LS's 8-color palette covers the most common corporate brand color combinations and school color pairings, making it suitable for large group uniform programs without custom color matching. For a short sleeve 65/35 Silk Touch counterpart, the K500 Silk Touch Polo coordinates directly. For a 100% polyester PosiCharge long sleeve performance upgrade, the K540LS Silk Touch Performance Long Sleeve Polo is the premium alternative. For a cotton-like performance hand feel in a short sleeve, the K568 Cotton Touch Performance Polo is a strong option. For a fine jacquard texture, the K528 Performance Fine Jacquard Polo offers a premium textured surface.

Wholesale & Program Buying Advantages

Uniform program coordinators and corporate apparel buyers choose the K500LS for year-round programs that need long sleeve coverage without sacrificing the proven Silk Touch fabric quality and easy-care performance that makes the K500 family the most trusted polo blank in the wholesale market. The long sleeve silhouette is particularly valuable for outdoor staff, hospitality programs in cooler climates, and corporate environments where a more formal, covered appearance is preferred or required by dress code.

The extended size run from XS through 6XL is a significant advantage for large organization uniform programs that need to outfit staff across a wide range of body types in a single consistent style. The 8-color palette covers the most common corporate brand color combinations, and the easy-care 65/35 poly/cotton construction resists shrinkage and wrinkles through repeated laundering — maintaining consistent appearance standards across the full program lifecycle. The K500LS pairs directly with the short sleeve K500 Silk Touch Polo and the performance K540LS Silk Touch Performance Long Sleeve Polo to build a complete long sleeve uniform system across fabric constructions.
