The FOX Defend Fire Alpha Jacket is a men’s MTB jacket built for cold-weather rides, delivering warmth, breathability, and durability for trail and enduro sessions. It’s designed to keep you comfortable when temperatures drop, without restricting movement.

With strategically placed Polartec® Alpha insulation, it keeps key areas warm while preventing overheating during hard efforts. The Stretch Cordura® fabric adds abrasion resistance and maximum mobility, making it ideal for aggressive riding.

Bonded cuffs with lycra gussets help block cold air from entering the sleeves, while a rear zip pocket provides extra bike-friendly storage for essentials.
