The Alpinestars Primary Jacket is constructed from a 92 % polyester/8 % spandex woven fabric that delivers a 5 kPa waterproof rating. The outer layer is treated with a clean TPU coating and a durable water‑repellent (DWR) finish, while a fleece lining provides additional warmth. The soft‑shell construction offers a wind‑stopping surface that retains the jacket’s lightweight, flexible feel.
Designed for motorcycle use, the jacket features a removable hood with bungie adjusters, on‑seam hand pockets, ribbed cuffs, and a ribbed hem for a secure fit. Internal and external labels provide brand identification, and high‑definition logos are printed on the chest and left sleeve.
