RUNNER'S WORLD GEAR OF THE YEAR 2025
Breathable wind and water-resistant shell for transitional weather and everyday wear. Made from our signature Japanese Primeflex™ fabric, with 3 zip pockets for essentials, a two-way zipper for temperature regulation, and laser-cut underarm holes for ventilation. Packs into its own pocket for easy storage.
Unlike other performance fabrics, the Toray PrimeFlex has a unique spiral yarn that not only gives this fabric a built-in mechanical stretch for 360° flexibility, but it will stretch and recover without using heavier water-absorbing elastics like Spandex. It also boasts an outstanding amount of comfort, breathability, and abrasion-resistance at only 40% of the weight of the old-school stretchy stuff. Partially made from a corn-based material that uses less water during the manufacturing process, the Primeflex fabric is both environmentally conscious and technologically advanced—elevating your running experience from mile one to mile one hundred.
The Graves PX Shell runs true to size, with a modern athletic fit designed to fit comfortably over a tee. If layering with heavier mid layers such as insulated pieces, consider sizing up.
Model is 6’1”, wearing size medium.
Garment measurements are listed in inches. These measurements are approximate and actual garments may vary up to ½”. See attached photo for sizing help.
