Product Insights & Style Tips

The Eiger Speed IN 1/2-Zip Hoodie from Mammut is built for the moment the climb tops out and the belay starts. It lives compressed in its own chest pocket until the wind picks up, then deploys in seconds to keep the chill from cutting into the effort you just put in. The core is insulated with 900-fill DRYDown, while body-mapped PrimaLoft Gold Active targets warmth and moisture management at the forearms, shoulders, and hood. A 2-way half zip delivers on-the-move ventilation, and the low-profile elastic hem and cuffs seal in heat without adding bulk under a shell.

At 254 grams this hoodie pulls its weight without weighing you down. The hood is adjustable to seal out wind at exposed summits, and the elastic hem and cuffs lock warmth in under a shell. It packs into its own chest pocket for fast, compact carry, so you can stash it when the climb heats up and pull it out at the belay without missing a beat. The setup balances insulation and mobility, keeping the core warm while hands stay unencumbered for climbing tasks.

Made with recycled materials and responsibly sourced down, the Eiger Speed nods to Mammut's performance ethos with a lighter footprint. An ultralight insulated layer built for alpine and ski touring, it sits ready for the moment weather shifts and the route demands a quick, warm transition.
