Use measurements, not letter labels, to pick your Sergio Tacchini track jacket size. A step-by-step method for Via Track Jacket and Nota Knit Jacket fits.
Quick answer
Measure your chest at the fullest point, add 2-4 inches for a classic track jacket fit, then match that number to the Sergio Tacchini sizing chart rather than your usual letter size. The Via Track Jacket is cut for easy athleisure layering, while the Nota Knit Jacket has a more refined knit fit, so the same letter can feel different across both.
Start with your chest measurement, not your usual size
Your letter size from other brands tells you very little about how a Sergio Tacchini track jacket will sit. Chest circumference is the number that matters most, because track jackets are designed to close at the front and move with your shoulders. Measure around the fullest part of your chest, keeping the tape level under your arms and snug but not tight. If you are between two numbers, round up for a relaxed fit or stay at the lower number for a closer fit.
Decide how you want the jacket to sit
Track jackets are not one fixed fit. A classic look leaves room for a T-shirt or light knit underneath and allows the zip to close without pulling. A closer fit sits near the body and works better over a base layer. The Via Track Jacket is described as an athleisure design for resort lounging and active pursuits, made of washed poly nylon for ease and comfort, so it is cut to move. The Nota Knit Jacket is a knit jacket with ribbed side panels and an open mesh stitch at the sleeves, which gives it a more structured, refined silhouette. If you want the same ease in both, take your chest measurement plus 2-4 inches.
Compare sleeve and body length to jackets you already own
Chest is the starting point, but sleeve and body length decide whether the jacket looks intentional. Lay a track jacket you already like flat on a bed and measure from the highest point of the shoulder to the end of the cuff, then from the base of the collar to the hem. Compare those numbers with the Sergio Tacchini sizing chart for the style you are considering. If your current jacket has raglan sleeves, as the Via Track Jacket does with contrast piping at the raglan sleeves, measure from the collar seam rather than a shoulder seam to keep the comparison fair.
Check the fabric before you lock in a size
Fabric changes how a jacket feels on the body. The Via Track Jacket uses washed poly nylon, which has some give and suits a relaxed fit. The Nota Knit Jacket is spun from Athena yarn, an eco-conscious viscose blend with breathability, moisture-wicking performance, and a soft hand feel, and it is finished with ribbed side panels. Knit fabric follows your shape more closely than woven nylon, so if you want a loose layer, size up in the knit and keep your measured size in the track jacket. When a product page does not list a specific measurement, treat that as a limitation and rely on the general sizing chart plus your own jacket measurements.
Your step-by-step sizing routine
- Measure your chest: Wrap a soft tape around the fullest part of your chest, level under the arms, keeping it snug but not tight. Write the number down in inches or centimeters and stay consistent. Checkpoint: the tape should not slide down or dig in. If it does, remeasure.
- Add your preferred ease: Add 2-4 inches to your chest measurement for a classic track jacket fit that closes over a T-shirt. Add 0-2 inches for a closer fit over a base layer. Common mistake: using your suit or dress-shirt size, which is cut for a different layer.
- Match the number to the sizing chart: Find your chest measurement on the Sergio Tacchini sizing chart and choose the closest size. If you are between sizes, go up for a relaxed fit and down for a trim fit. Checkpoint: the chart is the reference, not the letter on your other jackets.
- Adjust for the style and fabric: For the Via Track Jacket, a washed poly nylon style with raglan sleeves, your measured size usually works. For the Nota Knit Jacket, a knit with ribbed side panels, size up if you want a looser layer. Common mistake: assuming every Sergio Tacchini jacket fits the same across fabrics.
- Compare against a jacket you own: Lay a jacket you like flat and measure the chest, sleeve, and body length. Compare those numbers with the chart before you order. Next step: if the numbers sit between two sizes, choose the one that matches the fit you want, not the one you usually buy.
How these two styles fit differently
- Via Track Jacket-Honey Gold: The Via Track Jacket is made of washed poly nylon for ease and comfort, with contrast piping at the raglan sleeves and hand pockets. The raglan sleeve construction and washed nylon give this jacket a relaxed, movement-friendly fit, so your measured chest size is usually enough.
- Nota Knit Jacket- Maritime Blue: The Nota Knit Jacket is spun from Athena yarn, an eco-conscious viscose blend with breathability, moisture-wicking performance, and a soft hand feel, and is knit with ribbed side panels and an airy open mesh stitch at the sleeves. The knit fabric and ribbed panels follow the body more closely than nylon, so if you want a looser layer, consider sizing up in this style.
