Inselberg introduces the Centile Hoody, an advanced technical layer engineered for alpine conditions. Leveraging a hybrid insulation system that precisely maps 850-fill power Expedry down with strategic synthetic insulation placement, this hoody delivers optimized thermal regulation and moisture management in the harshest environments.

The Centile Hoody has undergone rigorous testing in some of the world's most extreme conditions. It was field-tested on Mount Everest by Mike Hamill and the CTSS (Climbing the Seven Summits) guide team, ensuring its reliability in high-altitude, cold-weather scenarios. The jacket's hybrid construction enhances performance in key areas: Expedry down, with its gold-fusion technology, delivers superior moisture resistance, keeping the core insulated in cold, dry conditions. Meanwhile, synthetic insulation is expertly mapped to high-wear, high-moisture zones such as the cuffs, collar, hood, armpits, shoulders, and elbows—areas where synthetic insulation's hydrophobic properties and durability excel.

"We developed the Centile Hoody to push the boundaries of hybrid insulation technology," explains Inselberg Founder, Jarlath Anderson. "Our goal was to create a piece that doesn't just keep you warm but actively manages moisture and durability where it's needed most. The Expedry down is a game-changer, offering exceptional warmth and moisture resistance, while the synthetic mapping ensures that critical areas stay dry and resilient against friction and wear."

The jacket is engineered for the rigorous demands of alpine climbing, ski mountaineering, and winter trekking. Articulated patterning and an adjustable, helmet-compatible hood allow for full freedom of movement, critical when navigating technical terrain or layering under a shell.

Environmentally Engineered

The Centile Hoody also reflects Inselberg's commitment to sustainability. The face fabric is constructed from a 10D bio-nylon derived from corn oil, reducing the jacket's environmental footprint. A PFC-free DWR finish ensures water repellency without the use of harmful fluorocarbons, while the down insulation is certified to the Responsible Down Standard (RDS), guaranteeing ethical sourcing.

"While performance was our primary focus, we made no compromises on sustainability," Jarlath adds. "We're using bio-based nylon for the first time in a piece like this, alongside our commitment to RDS down and PFC-free finishes. The Centile Hoody is proof that high performance and sustainability can coexist."
