Immersion Research - Alpha Hoodie

Built for stop-and-go adventures, the Alpha™ Hoodie hits the perfect balance of lightweight insulation and exceptional breathability. Its unique mesh-like knit lattice and lofted fibers trap just enough heat to keep you comfortable, while allowing excess moisture to escape when activity levels rise.

Designed to shine as a mid-layer, the Alpha™ Hoodie layers effortlessly over a base layer and under a shell. A high collar and snug-fitting hood add extra protection against cold exposure, while the compressible design packs down small when conditions warm up—ideal for easy stow-and-go versatility.

Perfect for high-output days when adaptability matters most.
