Men's Alpha Flash Fleece Jacket

Inspired by the latest innovations in fabric technology the Rab Men's Alpha Flash Fleece Jacket radically reinvents the traditional mid-layer.

From long, cold expeditions with limited resources to fast and light mountaineering the Alpha Flash distils everything you need into one mid-layer. Made from the exceptionally breathable Polartec Alpha, the fabric wicks moisture at an incredible rate, keeping you warm and dry even when you're right at your physical limit.

With flexible fleece panels either side, Alpha Flash will never hold you back; moving with you no matter how strenuous the climb. Extremely packable the Alpha Flash boasts an impressive warmth to weight ratio, making it the alpinist's ultimate cold weather mid-layer.

Polartec® Alpha® Insulation

Polartec® Alpha® is a highly compressible and breathable insulation made of durable lofted knit fibres connected to a solid mesh core. Striking an equal temperature balance by limiting the cold air that enters the garment and moving excess heat away from the body, it's perfect for start stop activities and extreme mountain conditions.
