The Mammut Sender IN Hooded Jacket sits within Mammut's dedicated Sender collection, a line purpose-engineered for climbers and mountaineers who demand gear that performs at altitude without compromise. This insulated hooded jacket has been designed to deliver dependable warmth in the most demanding alpine environments, from multi-pitch winter routes to high-altitude expeditions.
Built for the Mountains
Mammut's Sender range represents the pinnacle of their climbing-focused design philosophy. Every element of the Sender IN Hooded Jacket has been considered with the vertical world in mind — from the helmet-compatible hood that provides full coverage without restricting visibility, to the climbing-harness-compatible cut that ensures pockets and hems sit clear of your gear loops.
Premium Insulation Technology
At the heart of this jacket is high-quality insulation that delivers an outstanding warmth-to-weight ratio. The insulated construction traps body heat efficiently while remaining lightweight and packable — essential attributes for any piece of kit that needs to earn its place in your pack. Whether worn as a standalone outer layer during belays or as an insulating midlayer beneath a hardshell, the Sender IN adapts to your layering system seamlessly.
