A lightweight, breathable outer layer for everyday training.

We designed the Session Jacketto be one of the most versatile and durable pieces in your training wardrobe, working just as well for warm-ups,long runs and recovery days. A streamlined stretch-knit jacket for shoulder seasons, made from asoft, high-stretch fabric with micro-mesh side panels for breathability.

The Session Jacket is designed for variable conditions: lightweight and packable, but with a warmer hand-feel that insulates better than a traditional windbreaker. It also has mesh panels under the arms and down the side panels, allowing for more breathability as temperatures rise. And unlike woven fabrics used in other jackets, the Session Jacket has high stretch and recovery for improved range of motion.

We started with Veloce fabric, a stretch knit made in Northern Italy by the masters of luxury performance textiles. It’s an 86% Nylon, 14% Elastane blend. It may sound complex, but the results are simple. It’s lightweight and durable, silky smooth, and performs under intense activity. It also breathes well, dries quickly, and insulates without risk of overheating – ideal for long runs that start cold and end warm, or warm-ups that start slow and end fast.

In places where heat tends to rise and moisture accumulates, we used panels of Bravio mesh - the same ultra-lightweight blend used in Tracksmith's Twilight pieces. It improves temperature regulation and, working together with the Veloce fabric, gives the body and sleeves a more efficient range of motion.

As every runner knows, attention to detail can make all the difference – whether it’s the fabric in Tracksmith's clothes, preparation for race day, or the small habits that go into better recovery. Tracksmith's Session Jacket features zipper pockets with room for keys, credit cards, or your iPhone X. Semi-elasticated cuffs allow for easier watch checking.

Jeanne, Lyndsay and Amy tested the Session Jacket over training tripsin early fall in the Berkshires and spring in Flagstaff:from the warm-upfor some dirt road fartleks to the first miles of the long run.
