Designed without a hood for seamless integration with helmets and shells, and featuring convenient upper pockets for harness-wearing accessibility, this jacket is your essential companion for year-round climbing and rappelling adventures

MAMMUT Taiss ML Jacket Men | High-Performance Thermal Fleece

Elevate your mountain performance with the MAMMUT Taiss ML Jacket for men, a premier technical mid-layer engineered for uncompromising athletes who demand versatility and reliability. This high-performance synthetic thermal jacket is meticulously crafted to function as a core component of your layering system throughout the year. Designed without a hood for streamlined integration with outer shells and helmets, its primary focus is on delivering exceptional warmth, breathability, and unrestricted movement for all your alpine pursuits.

At the heart of the Taiss ML Jacket´s superior performance is its advanced material, which provides an exceptional warmth-to-weight ratio. This robust fleece is not only cozy but also highly durable and abrasion-resistant, capable of withstanding the rigors of rock, ice, and frequent pack use. The fabric’s impressive four-way stretch works in harmony with your body, ensuring that every reach, stretch, and climb is met with complete freedom of movement. The jacket’s Athletic Fit contours to your body, eliminating excess bulk for efficient layering without ever feeling restrictive. This close-to-body fit also enhances the material´s thermal efficiency, trapping heat where you need it most while allowing for dynamic motion.

Intelligently designed for the vertical world, this men´s jacket excels in moisture management. It actively wicks perspiration away from your skin to the surface, where it can quickly evaporate. This crucial function helps maintain a stable and comfortable microclimate, preventing the dangerous post-exertion chill often experienced during rest periods or on windy summits. Flatlock seams are utilized throughout the construction to minimize friction and prevent chafing, ensuring next-to-skin comfort even when worn for extended periods under a harness or backpack.

Designed for year-round mountain adventures.

Made with Polartec Power Stretch fleece, this breathable mid-layer keeps you warm even at high altitudes.

Its moisture-wicking properties help regulate temperature to minimize rapid cooling at the summit.

Thumb loops provide a secure fit for layering under a jacket.

Upper pockets offer easy access to your gear when wearing a harness or pack.

The Taiss ML Jacket is an ideal mid-layer for both climbing and rappelling.
