Men's Senja Alpha90 Hood

The Norrøna Men's Senja Alpha90 Hood is built for trail runs where the pace changes, the weather moves around, and you need one layer that can keep up. It’s a warm, airy hybrid fleece that combines insulation with partial wind resistance, giving you more protection in the front and higher breathability in the back. That makes it especially useful on longer efforts or variable days when stopping to swap layers gets old fast.

Norrøna uses Polartec® Power Grid fleece here for stretch, durability, and a strong warmth-to-weight ratio, then adds Polartec® Alpha insulation for consistent warmth while releasing excess body heat during activity. A recycled nylon face fabric keeps weight low while adding breathability and solid wind protection. The technical fit, slightly longer back, and trail-ready details make this a practical piece for runners, but it also works well for any activity where you want light insulation up front without trapping too much heat overall.
