Push for Progress

Shoulder seasons call for a versatile jacket that can be warm enough for crisp morning sessions and light enough to feel barely there when the intensity increases. In the long and short, it must move with you. Whereas traditional shells have no stretch and can feel like running in a garbage bag, the Session Jacket is lightweight and breathable with a high-stretch range of motion.

Luxurious Performance

Our Session products are built for everyday training, so they prioritize comfort and durability. One part of the formula is our Veloce Blend: a luxurious high-stretch knit made in Italy that drapes and moves with your body. Soft and silky, it 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.

Finer Points

As every runner knows, attention to detail can make all the difference – whether it’s the fabric in our clothes, our preparation for race day, or the small habits that go into better recovery. Our Session Jacket features zipper pockets with room for keys, credit cards, or your iPhone X. Semi-elasticated cuffs allow for easier watch checking and the high collared neckline can be worn up or down depending on the temperature.

Road Tested

Marathoners Ruben, Mick and Mike put the new Session Jacket through its paces over three days of hard running in the Berkshires, from the first few miles of a morning 20 mile long run to the cool down after a fartlek workout.
