Switch Men's Pontetorto® Wind Resistant Insulated Vest - Fern

Active insulation for fast mountain movement

The Mountain Equipment Switch Men's Vest combines a 20D RS Nylon outer, Octayarn Warp-knit lining and Pontetorto® Tecnostretch 187 fleece to create a highly breathable active-insulation layer for demanding mountain sports. Designed for alpine climbers and ski tourers, it provides core warmth, moisture management and wind resistance during high-output activity. No verified temperature rating or weather threshold has been supplied.

Performance & Engineering

• Octayarn Active Insulation. Engineered with Octayarn Warp-knit lining, using hollow multi-dentate fibres that trap warm air while accelerating moisture transfer, helping maintain comfort during steep ascents and sustained aerobic efforts.

• Wind-Resistant Front Panel. Built with lightweight 20D RS Nylon outer fabric featuring mechanical stretch, providing wind resistance and unrestricted movement when travelling quickly through exposed mountain terrain.

• Targeted Breathability. Designed with Pontetorto® Tecnostretch 187 fleece across the back and side panels, allowing excess heat and moisture to escape while maintaining a low-profile fit underneath shells and packs.

• Technical Layering Efficiency. Engineered as an active insulation piece that can remain in place throughout changing exertion levels, reducing the need for constant layering adjustments during ski tours and alpine routes.

• Harness-Friendly Packability. Built to pack into its own pocket with twin karabiner carry loops, allowing easy attachment to a harness or compact storage inside a pack when conditions change.
