The Alpinestars SMX Waterproof Jacket combines advanced safety features with versatile comfort for riders seeking reliable protection in various weather conditions. Designed with a durable poly-fabric and stretch softshell chassis, this jacket offers both durability and lightweight flexibility, ensuring maximum mobility during rides. The integrated 2L waterproof membrane and DWR-treated fixed waterproof membrane provide excellent wet weather performance, keeping you dry in rain or snow while maintaining breathability. Strategically placed stretch panel inserts allow for expansion when using the Tech-Air® 5 airbag system, which is fully compatible and requires no bike-to-rider setup, offering an added layer of safety without compromising fit or comfort. The jacket’s engineered sports body mapped fit and precurved sleeves optimize riding performance by providing a tailored fit that moves with the rider. The detachable thermal liner, with 100g insulation in the body and 80g in the sleeves, allows customization for different climates, making this jacket suitable for year-round riding. Safety is enhanced with Nucleon Flex Plus armor on the shoulders and elbows, providing certified impact protection, while the optional Nucleon chest and back protectors can be purchased separately for extra security. The DFS Lite shoulders feature dynamic friction shields that improve abrasion resistance, and the low-profile sports collar with soft lining enhances comfort during extended rides. Additional thoughtful features include an elongated rear for better coverage, a shock cord waist for a secure fit, and multiple pockets—two front zippered pockets, two chest pockets, an inner waterproof document pocket, and inner pockets on the liner—providing ample space for valuables and essentials. The zip front closure is engineered for durability and ease of use, making this jacket a practical choice for serious riders who demand safety, comfort, and all-weather performance.
