The best motorcycle journeys rarely come with perfect weather, and having the right jacket makes all the difference when the conditions change. The Alpinestars Arenis GORE-TEX Motorcycle Jacket is built for those long days in the saddle, combining dependable waterproofing, ventilation and impact protection with the flexibility you need for touring, winding roads and off-road adventures.Here's what makes the Alpinestars Arenis GORE-TEX Motorcycle Jacket a practical choice for your next ride: 200D 2-Layer GORE-TEX Laminated Shell: Nobody wants to spend hours riding in a soaked jacket. The lightweight, PFAS (per- and polyfluoroalkyl substances) free GORE-TEX laminated shell provides waterproof performance above 28,000 mm and breathability above 15,000 g/m²/24h, helping keep the rain out while allowing perspiration to escape. Its laminated construction also prevents the outer fabric from becoming heavily waterlogged, making wet-weather riding and drying out after a journey easier to manage. Direct Ventilation System: When the temperature rises, you can open the zipped arm vents and front Superairflow panel to bring fresh air into the jacket. Rear exhaust vents help warm air escape, giving you control over airflow during summer touring, slower off-road sections and changing temperatures throughout the day. Nucleon Flex Pro Level 2 Protection: CE Level 2 Nucleon Flex Pro protectors at the shoulders and elbows provide impact protection with a flexible, low-profile design. They follow your natural movements when steering, leaning into corners or standing on the footpegs, helping you stay comfortable throughout the ride. Articulated Stretch Construction: Pre-curved sleeves and stretch panels around the underarms and rear upper arms allow the jacket to move with you. Whether you're reaching for the handlebars, turning through tight bends or standing on the pegs, the construction helps prevent the jacket from pulling against your shoulders and arms. Soft-Seal Adjustable Collar: Cold wind and rain finding their way down your neck can quickly spoil a good ride. The Soft-Seal collar uses an adjustable shock-cord system to create a comfortable fit around your neck, helping keep unwanted draughts and moisture outside when the weather turns. Internal Volume Adjustment System: Riding in the morning chill and afternoon sunshine often means changing what you wear underneath. The internal volume adjustment system allows you to fine-tune the jacket's fit around your layers, helping keep it comfortably positioned whether you're wearing a lightweight base layer or additional insulation. Waterproof Storage Pockets: Waterproof cargo pockets and a chest pocket give you convenient places to store everyday essentials such as your wallet, keys and travel documents. An additional internal compartment provides extra storage, keeping frequently used items organised and within easy reach when you stop along the way. Waterproof Front Closure: The waterproof front zip works with a seam-taped flap and gusset construction to help prevent rain from entering through the jacket's main opening. This is particularly useful on longer motorway journeys, where sustained wind and rainfall can put your waterproof riding equipment to the test. Reflective Outer-Shell Details: Integrated reflective elements help make you noticeable to other road users when headlights shine on the jacket. They provide a useful visibility feature during early morning departures, evening rides, and journeys in fading light. Tech-Air Ready Construction: The jacket is designed to accommodate compatible Alpinestars Tech-Air airbag systems, giving you the option to add another layer of impact protection to your riding setup. Compatible with the following airbag options - Tech-Air Off-Road, Tech-Air 5 Plasma, Tech-Air 5, and Tech-Air 3 V2 System. Jacket-to-Trousers Connection Zip: The integrated waist zip allows you to connect the jacket to compatible Alpinestars adventure trousers, helping keep your riding kit securely positioned. It is particularly useful when standing on the footpegs, moving around the motorcycle or spending long hours in the saddle. CE AA-Class Certification: The jacket is certified to CE Category II EN 17092 AA-Class requirements for protective motorcycle clothing, confirming that its construction has been tested against recognised European standards for abrasion resistance, tear strength and seam strength. This gives you a recognised level of protection for road and adventure riding, helping you choose your riding equipment with a clear understanding of its protective performance.The Alpinestars Arenis GORE-TEX Motorcycle Jacket brings together the features that matter when you're spending serious time on your bike: reliable weather protection, adjustable airflow, and enough freedom to enjoy the ride. From an early morning motorway run to an afternoon exploring unfamiliar roads, its thoughtful construction helps you adapt to the journey without constantly worrying about your equipment. It's a practical addition to your motorcycle kit if you enjoy getting out on the road and want a jacket that's ready for the unpredictable nature of adventure riding.
