ALPINESTARS Stella SMX Air Jacket

Built for warm-weather street riding, this jacket delivers high airflow and sport-focused comfort in a women’s-specific fit. Designed with a ventilated layout inspired by MX DNA, it prioritizes breathability and freedom of movement while maintaining a lightweight, performance-oriented feel on the bike. Stretch zones support natural mobility in a riding position, and the expandable structure allows proper integration with Tech-Air® 5 airbag systems.

A detachable windbreaker liner helps manage airflow when conditions change, extending usability beyond peak summer heat. With its balance of ventilation, mobility, and on-road protection, it is well suited for daily commuting and weekend rides in warm climates.
