First, What Is a Harrington Jacket?
The Harrington is a lightweight, waist-length jacket, originally created for golfers. Its key features are a zip front, a stand-up collar with a two-button closure, ribbed cuffs and hem, and slanted flap pockets. The most iconic version, the Baracuta
G9, also features a distinctive Fraser Tartan lining and a unique vented back known as an "umbrella yoke." Its journey from the golf course in the 1930s to the shoulders of icons like Steve McQueen, Elvis Presley, and James Dean cemented its status as a versatile symbol of effortless cool.
The Set-In Sleeve: Structured and Sharp
The set-in sleeve is the most common type you'll find on jackets and shirts. The sleeve is a separate piece of fabric joined to the body of the garment with a seam that circles the shoulder at the armhole. This construction creates a defined shoulder line, giving the garment structure and a more tailored appearance. Think of a suit jacket or a crisp dress shirt—that sharp, clean shoulder is the work of a set-in sleeve. When applied to a Harrington jacket, it lends a more formal, put-together feel. The defined shoulders create a cleaner, smarter silhouette that pairs well with the collared, preppy elements of tenniswear.
The Raglan Sleeve: Sporty and Relaxed
The raglan sleeve tells a different story. Instead of a seam at the shoulder, it features a long, diagonal seam that runs from the underarm directly to the collar. This design was originally invented in the 19th century for Lord Raglan, who needed more arm mobility in battle after an injury. That origin story hints at its primary benefit: an enhanced range of motion. This functionality made it a longtime favorite for sportswear, most famously on baseball jerseys. On a Harrington jacket, a raglan sleeve removes the sharp shoulder line, creating a softer, more relaxed drape. It signals a casual, athletic heritage. The original Baracuta G9, in fact, uses raglan sleeves specifically for ease of movement, tying back to its golfing origins.
The Tenniswear Connection
The modern “tenniscore” aesthetic blends the sport's elegant heritage with casual comfort. It’s built on staples like crisp polo shirts, tailored shorts, clean white sneakers, and V-neck sweaters. It’s a look that is both athletic and refined, straddling the line between country club polish and contemporary streetwear. This is where the Harrington jacket fits in perfectly as the ideal outerwear piece. It's lightweight, sporty, and carries a preppy pedigree that complements the tennis aesthetic. But which sleeve is the right choice?
Making the Choice: Two Looks from One Jacket
This is where sleeve construction becomes a crucial styling decision. Pairing a set-in sleeve Harrington with a polo shirt and chinos creates a look that leans into the “smart” side of smart-casual. The structured shoulder of the jacket aligns with the collar and placket of the shirt, presenting a sharp, intentional, and more formal outfit. It’s a look that feels more rooted in the Ivy League and classic menswear traditions. Conversely, choosing a raglan sleeve Harrington instantly shifts the vibe towards the “sporty” end of the spectrum. The diagonal seams and softer shoulder create a more casual, relaxed silhouette that emphasizes comfort and mobility. It speaks the same language as the athletic roots of the polo shirt and sneakers. This combination feels more modern, effortless, and directly connected to the sportswear origins of both the jacket and the tennis aesthetic.
