Täsmä, a precision-response fabric.
Created for the fast-moving climates of northern latitudes around the globe, from Mt. Fuji to Mt. Foraker. The 3-layer fabric construction allows TÄSMÄ's dynamic inner membrane to adapt the rate of moisture transmission as the output of the user increases, assuring the perfect combination of protection, breathability and comfort, especially during activities that require unpredictable alternation between periods of high performance and repose, such as skiing and climbing.
Täsmä Fabric Technology
The flagship of our outerwear system has a new fabric technology - in collaboration with global textile leader Pertex Japan.
Täsmä has achieved the highest specifications of any technical outerwear fabric and will noticeably improve your mountain experience by keeping you dryer and warmer while reducing the weight of the garment. Maximum mobility is enabled by increased stretch and new patterning for FoM (Freedom of Movement).
Pairing the St. Elias Jacket with the St. Elias Bib creates a total integrated system for those with serious mountain ambitions.

THE TÄSMÄ STORY
The Mission: Improve safety in the backcountry. Protection from hypothermia. Keep backcountry users dry all day in the moisture-heavy conditions of the Japan Alps.
The Solution: In collaboration with Japan’s leading textile developers, we redefined breathability in shell fabrics—keeping the body drier, preventing chill, and lowering the risk of hypothermia in cold, wet conditions. At the same time, the system maintains full waterproofness, adds stretch, and maximizes long-term durability.
Through research and field testing in Hokkaido’s backcountry, these goals converged into a new fabric architecture: TÄSMÄ — a next-generation 3-layer system designed to move, breathe, and protect in perfect balance.
The Three Elements (3L) = TÄSMÄ System
The outer layer begins with a uniquely engineered face fabric using rhomboid-shaped filament yarns. This Diamond Fuse technology delivers double the abrasion resistance, superior water-shedding performance, and a refined technical sheen.
At the core, a dynamic membrane forms the barrier against rain and snow while allowing water vapor to escape through molecular diffusion. As the wearer’s output increases, so does the rate of moisture transmission —
up to 14,000 g/m²/day (MVTR).
To complete the system, a soft-knit backer is bonded to the membrane, efficiently drawing vapor away from the body to maintain dryness and comfort in motion.
Together, these three layers operate as a single, formidable system — balancing protection, breathability, and comfort in the most demanding conditions on the planet.
Every element is engineered to be as light, stable, and responsive as possible — delivering the most advanced cold-weather shell system available. Built for mountain professionals who spend 100+ days a year in the field.
Constructed entirely from recycled polyester, the mono-material design ensures full recyclability at end of life.
