Mammut Alto Waterproof Windproof Jacket - S - Black

Its primary benefit is providing advanced waterproof and windproof protection while maintaining breathability for comfort during strenuous outdoor activities.

While stylish, its ergonomic, movement-focused design is optimized for athletic use. It may feel more restrictive than a typical casual jacket.

Machine wash on a gentle cycle with cold water and mild detergent, then tumble dry on low or hang dry. Periodically reapply a DWR treatment.

Yes, the jacket is designed to be layered. You can wear base layers and mid-layers like a fleece underneath, depending on the temperature and activity.

Fully sealed seams mean that the stitching lines are covered with a waterproof tape, preventing water from entering through the needle holes.

The hood typically features drawcords or toggles that allow you to cinch it around your face for a secure and protective fit against wind and rain.

It is best suited for hiking, trekking, mountaineering, climbing, and other activities where protection from the elements and freedom of movement are essential.

Ensure the jacket has been properly washed and dried, and that the DWR treatment is still effective. Reapply DWR treatment if necessary.

Open zippers for ventilation if available. Ensure you are not wearing too many insulating layers underneath for the current activity level and temperature. The breathability of the fabric may be maximized by managing internal moisture.

Gently try to move the zipper. If it snags, check for any fabric caught in the teeth. Use a graphite pencil or a specific zipper lubricant on the teeth if it continues to be stiff.
