When pace, weather, and terrain are all in flux, the Senja Alpha90 Hood steps in as a finely balanced layer built for motion. Engineered for trail running but versatile across high-output pursuits, it delivers warmth where exposure demands it and breathability where effort generates heat—keeping your system in equilibrium from climb to descent.
The construction is a precise blend of advanced materials. Polartec® Alpha 90 insulation lines the front and shoulders, offering active warmth that continuously releases excess heat as intensity rises. Through the core and back, Polartec® Power Grid™ fleece enhances moisture transfer and airflow while maintaining an exceptional warmth-to-weight ratio. A lightweight ripstop nylon face fabric adds targeted wind resistance, shielding key zones without compromising breathability.
Everything about the fit and finish is designed to move with you. The close-fitting hood layers cleanly under a beanie, while articulated sleeves and thumbhole cuffs ensure a secure, no-shift feel during long efforts. A slightly extended back hem provides added coverage in motion, and a zippered chest pocket keeps essentials within reach. Reflective elements round out the build, adding visibility when your runs stretch into low light.
