Specialized Trail Alpha Men’s Mountain Bike Jacket – Polartec® Alpha® Insulated MTB Jacket for Cold-Weather Riding

Conquer cold-weather rides with the Specialized Trail Alpha Men's Mountain Bike Jacket, a high-performance insulated jacket engineered specifically for mountain biking in cool, damp, or unpredictable conditions. Featuring Polartec® Alpha® active insulation, this technical MTB jacket delivers lightweight warmth, exceptional breathability, and quick-drying performance, perfect for trail rides, bikepacking, or post-ride hangouts.


Advanced Polartec® Alpha® Insulation for Warmth & Moisture Control

The Trail Alpha Jacket uses Polartec® Alpha® insulation, designed for high-output activities like mountain biking. It provides thermal regulation and superior moisture-wicking properties, quickly evaporating sweat to keep you dry, warm, and comfortable even during intense climbs and descents.

Breathable & Stretchy Outer Shell for On-the-Bike Mobility

The durable outer shell is made from a flexible nylon/spandex blend, allowing for full range of motion on the bike while helping move moisture away from the insulation to the outside, keeping you drier for longer. Whether you're riding singletrack, gravel, or flow trails, this MTB-specific jacket performs through changing terrain and effort levels.

Versatile Style – On and Off the Trail

With a relaxed, casual look, the Specialized Alpha MTB Jacket transitions seamlessly from trail to town. Enjoy a drink post-ride or stay cozy around the campfire without missing a beat, this is your go-to mountain bike jacket for both function and style.

  • Polartec® Alpha® active insulation for lightweight, breathable warmth
  • Soft inner lining evaporates sweat quickly to keep you dry
