Meaning “descendant of ice" in Old Norse, Isleif is the ultimate expression of a lightweight waterproof hardshell.

At just 250g, it carries a hardshell’s defence in a windbreaker’s weight. Precision-cut, highly breathable, waterproof, and built for the fast, mixed-condition days where weight, protection, and freedom matter in equal measure.

Crafted from Pertex® Shield 3-layer fabric with NetPlus® recycled nylon, it delivers a storm-grade 20,000mm hydrostatic head combining serious waterproofing with mechanical stretch — a rare balance of resilience and comfort in a lightweight form. Fully taped seams, a PFC-free DWR finish, and a durable 30-denier ripstop face fend off rain, wind, and snow.

A close, athletic cut keeps bulk to a minimum, while articulated sleeves and a scoop drop hem move with the body. A storm hood with mouldable peak locks down vision when the weather breaks. Pre-elasticated cuffs, low-profile hem adjusters, and AquaGuard® waterproof zips seal out the elements without excess.

Packing into its own pocket, Isleif carries light but hits far above its weight. An uncompromising shell for those who demand speed, endurance, and relentless reliability.

Hardshell Power. Windbreaker Weight.
