Ralph Lauren Polo Pony Quarter-Zip Mock-Neck Sweater – Blue – Men’s MNPOSWE16822310-400

Ralph Lauren Polo Pony Quarter-Zip Mock-Neck Sweater – Blue

The Ralph Lauren quarter-zip in its most considered yarn construction. This mock-neck long-sleeve sweater is built from a four-fiber engineered blend: 40% wool / 30% nylon / 15% anti-pill acrylic / 15% cotton — each fiber present for a specific performance function that the others cannot substitute. Wool for warmth and natural fiber drape. Nylon for tensile strength and abrasion resistance at the rib zones. Anti-pill acrylic to suppress surface pilling across the garment body under repeated wear. Cotton to soften the skin-contact feel and reduce the residual scratch of the wool-nylon base. The polo pony embroidery sits at the left chest in white against the blue ground — the house credential at its most legible contrast. The quarter-zip mock-neck adds adjustable ventilation and a structured collar profile that a crewneck cannot produce. Ribbed cuffs and hem complete the construction. Standard fit, designed for men.

Why You’ll Love It

• 40% Wool – Warmth Core & Natural Drape: Wool at 40% of the blend composition — the primary fiber and the highest single-fiber percentage in the blend. At this proportion, wool provides the primary warmth function: the natural fiber crimp that traps air within the yarn structure and retains body heat across the full garment. Wool at 40% also provides the primary drape character: the natural weight and flexibility that gives the sweater its relaxed, body-following hang rather than the stiff or synthetic drape of an acrylic-dominant blend. The wool component that makes this sweater read and wear as a natural-fiber garment while the remaining three fibers address the specific performance limitations that pure wool cannot overcome.
• 30% Nylon – Tensile Strength & Rib Durability: Nylon at 30% — the second-highest fiber proportion in the blend, present for the structural function that wool and cotton cannot provide at this garment type. Nylon adds tensile strength to the yarn: the fiber that resists the pulling and stress that knit fabric sustains at high-movement zones — the underarm, the cuff rib termination, the quarter-zip placket edge. At the ribbed cuffs and hem, nylon contributes the elastic recovery durability that keeps the rib returning to its original gauge after repeated stretch cycles over the garment’s wear life. The nylon component that makes this sweater’s construction hold its form and its rib structure through regular wear and washing rather than relaxing out of shape after the first season.
• 15% Anti-Pill Acrylic – Surface Pilling Suppression: Anti-pill acrylic at 15% — the fiber that addresses the most common long-term wear failure of wool-blend knitwear: surface pilling. Standard acrylic and wool blends pill at the surface because the short fiber ends work out of the yarn structure under friction and entangle into surface pills. Anti-pill acrylic uses a modified fiber structure that anchors the fiber end within the yarn and resists the fiber-end migration that causes pilling. At 15%, the anti-pill acrylic component suppresses surface pilling across the full garment body — the chest, the sleeves, and the back panel — under the friction of regular wear, bag contact, and repeated washing. The fiber that keeps the blue surface clean and pill-free through the garment’s full wear life.
• 15% Cotton – Skin-Contact Softness, Scratch Reduction: Cotton at 15% — the fiber that modifies the skin-contact feel of the wool-nylon base blend. Wool and nylon both have surface friction characteristics that can produce a scratchy or coarse skin-contact feel at the neck, wrists, and any zone where the knit sits directly against the skin. Cotton fiber, at its natural smooth surface, reduces the overall surface friction of the blended yarn: the cotton fiber ends at the yarn surface interrupt the wool and nylon fiber ends that produce the scratch sensation. At 15%, the cotton component does not reduce the warmth or structural performance of the wool-nylon base — it modifies only the skin-contact register, making the mock-neck collar and ribbed cuffs comfortable against bare skin for the full duration of wear.
• Quarter-Zip Mock-Neck – Adjustable Ventilation, Structured Collar Profile: A quarter-zip placket at the mock-neck collar — the closure format that gives this sweater a functional capability that a crewneck cannot provide: adjustable ventilation at the neck. Fully zipped: the mock-neck collar stands at the throat, sealing the collar zone against cold air and framing the face with the structured profile that is the Ralph Lauren mock-neck’s silhouette signature. Partially unzipped: the collar opens to allow ventilation and body heat release during activity or in transitional temperatures. The quarter-zip that makes this sweater perform correctly across a wider temperature range than a fixed-neck crewneck construction.
• Polo Pony Embroidery – Left Chest, White on Blue: The Ralph Lauren polo pony embroidery at the left chest — the house credential in white against the blue ground, the highest-contrast placement the colorway allows. The polo pony at the quarter-zip mock-neck’s chest position: the credential visible when the jacket or outerwear layer is open, the first mark read at medium range against the blue body. The embroidery that does not compete with the quarter-zip hardware at the collar — two Ralph Lauren credential elements (the pony embroidery and the branded zip pull) at different positions and different scales, each readable independently.
• Ribbed Cuffs & Hem – Knit Termination, Fitted Close: Ribbed knit cuffs and hem — the rib termination that closes the sweater at the wrist and hip with a fitted, elasticated edge that returns to its original width after stretching. The rib construction that prevents the cuffs from flaring open at the wrist and the hem from dropping or distorting at the hip over repeated wear. In the four-fiber blend, the nylon component contributes to the rib’s elastic recovery durability; the anti-pill acrylic contributes to the rib’s surface resistance at the high-friction wrist contact zone.
• Standard Fit – Men’s: A standard, regular fit — proportioned for men with a straight body, set-in sleeves, and a mock-neck collar height that works with or without a shirt collar underneath. The fit that reads as classic Ralph Lauren: neither slim nor oversized, the proportions that have defined the brand’s knitwear silhouette across seasons.
