The Spidi Alpentrophy H2Out jacket was developed from scratch to be one of the world's best motorcycle touring jackets, combining safety, comfort, and a genuine four-season fit.

Each jacket is CE EN 17092-3:2017 Class AA certified, as well as removable ForceTech and Warrior Lite protectors (CE EN 1621-1:2012 Level 2 certified) at the shoulders and elbows. The Alpentrophy H2Out's main chassis is constructed from a combination of waterproof, breathable, and windproof H2Out laminated Cordura®, a high-tenacity polyamide fabric, and a triple-twisted Extra Tenax Nylon 6.6, both highly resistant to abrasion and puncture.

A removable 150-gram thermal liner comes standard, along with neoprene inserts, 3M® Scotchlite® reflective zones, and multiple vents designed to keep the rider cool on hot days. The Alpentrophy uses the Ergofit integrated adjustment system to ensure a perfect fit and is also equipped with the E.S.T. device for micrometric adjustment of the collar.

For added safety, a jacket-to-pants zipper is standard, and each jacket has waterproof external pockets and waterproof internal pockets. For those seeking the maximum possible protection, the jacket can be upgraded with optional back and chest protectors.
