SEASONS OF CHANGE

 Runners require a versatile jacket that works across a range of temperatures and distances. The Session Jacket, with its unique stretch-knit body fabric and mesh side panels, is engineered to address these conditions. It insulates, breathes, and dries quickly, all while stretching to match your stride. The Session Jacket sets a new standard for shoulder seasons. 

BETTER RANGE

Inconsistent temperatures and unexpected precipitation are a fact of  training and racing outdoors. So rather than the traditional shell that might keep you dry in a downpour, but otherwise feels like you’re running in a garbage bag, runners need a jacket that performs in a wide range of conditions. The Session Jacket is lightweight but has a warmer hand-feel that insulates better than a traditional windbreaker. It also has mesh panels under the arms and down the side panel, allowing for more breathability as temperatures rise. And unlike non-stretch woven fabrics used in other jackets, the Session Jacket has high stretch and recovery for improved range of motion.

EFFORTLESS VELOCE

The brief for the Session Jacket was clear: build a jacket that feels effortless on both the warm-up and the long run. To achieve this goal, we started with our 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. 

MADE TO MOVE

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

THE 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 a light hood provides additional protection against unexpected rain.

ROAD TESTED

New England isn't the only place with fickle weather. When we woke to unseasonably cool temperatures in Arizona, Mike and Ruben wore their Session Jackets for a 19 mile run before the sun started to shine in earnest. Earlier in the week, the athletes wore them to warm up before a 6 x 1 mile workout at 5:30 pace.
