Details & care
Transition seasons and variable mountain days demand a layer that can keep up with changing conditions without requiring a gear swap every hour, and the Mammut Sender IN Hybrid Jacket was designed to handle exactly that. Whether it is worn under a shell on a cold ski tour, thrown on at the belay station on a cool climbing day, or used as the outermost layer on a brisk autumn hike, this jacket adapts to the moment rather than defining it. The wind-repellent recycled outer fabric with PFC-free DWR treatment blocks light weather and moving air while still breathing well enough for sustained effort. What makes the Sender genuinely different is the insulation underneath. Mammut's LOOPINSULATION fill is made from recycled rope production offcuts, turning manufacturing waste into a high-performing synthetic fill that delivers consistent warmth without cold spots. Brick-lay engineered 3D baffles with offset seams eliminate the gaps that standard baffle construction leaves behind, keeping warmth evenly distributed across the body. Raglan sleeves and stretch fleece side panels open up the jacket's range of motion and actively manage temperature during high-output movement. A storm flap behind the front zipper adds a layer of weather protection at the most exposed seam, and two zippered side pockets keep essentials secure throughout the day.
