The Aeroshell WP Jacket is a waterproof softshell motorcycle jacket designed for the style-conscious rider of a naked bike, scooter or even an adventure tourer. This motorcycle jacket combines a modern cut with proven wet-weather performance.
The outer shell is a stretchy, soft outer layer that provides a good fit and excellent flexibility. It barely feels like a motorcycle jacket. The hoodie-style design emphasises that even more. The cut is sporty, clean and straight, with overlapping ventilation openings for good breathability and plenty of climate comfort.
An integrated waterproof membrane with taped seams keeps you dry in the rain. The water-repellent front zip seals effectively, backed up by an internal storm flap. At the top, a ‘zip garage’ (we love that term) prevents the puller from tapping annoyingly against your chin while riding. The hood is fixed. To avoid it ballooning at speed, you can secure it, and a dedicated air vent also helps. It is all smartly put together.
Ergonomic sleeve ends (stretch and Velcro) and the lower hem are designed for an optimised, comfort-focused fit. The adjustable cuffs ensure a precise closure. The zippered hand pockets are partially hidden and follow the clean styling. No distracting details, but sufficient storage, complemented by an internal pocket. Waist adjusters are also neatly concealed.
An elastic Belt Loop with press stud creates a secure connection to almost all Alpinestars motorcycle trousers and/or motorcycle riding jeans.
Nucleon Flex Plus Level 1 shoulder and elbow protectors provide solid impact protection in an ultra-flexible, ventilated, low-profile design. You can upgrade the motorcycle jacket with an optional Nucleon Plasma chest protector and Nucleon Plasma back protector.
This motorcycle jacket is certified as CE Category II PPE under Regulation (EU) 2016/425 – Class A.
