The Mammut Taiss ML Hooded Jacket Men is a technical midlayer developed for year-round use in the mountains. According to the manufacturer, it is designed for high-altitude activities and changing conditions, combining warmth, breathability, and effective moisture management to help maintain stable comfort both during movement and after reaching the summit. 

The jacket is made with Polartec® Power Stretch™ fleece with 4-way stretch, providing excellent elasticity, quick-drying performance, and reliable shape retention over time. The fabric wicks moisture efficiently and supports temperature regulation, while the very good warmth-to-weight ratio makes the model a strong choice for intensive mountain activities across multiple seasons.

It comes in an Athletic Fit, offering a close and precise fit without restricting movement. For even greater functionality, the model features a fitted hood that can be worn under a helmet, along with an elasticated hood border for a more secure feel. The functional underarm gusset enhances freedom of movement, which is especially valuable for climbing, alpine hiking, and technical terrain.

The Taiss ML Hooded Jacket Men is equipped with two zippered pockets that are compatible with both backpacks and climbing harnesses, making it especially practical when easy access to storage is needed on the move. Additional comfort comes from the comfortable thumb loops and flat seam construction, which help reduce chafing under backpack straps. The embroidered Mammut logo completes the clean technical look of the jacket.

At 370 g, the jacket balances effective warmth with practical portability. Based on the manufacturer’s activity ratings, it is especially suitable for climbing, hiking, mountaineering, trekking, and alpine climbing, while also being a strong option for freeriding. The product carries Polartec® Power Stretch®, bluesign® PRODUCT, Fair Wear, and Recycled labels, making it a strong choice for users who want technical performance with a more responsible material profile.
