The Breach Jacket matches high insulation with durability for extreme cold weather. This men's black insulated jacket packs 850 fill power goose down for sub-zero conditions. Combining Pertex® Quantum Pro fabric with Spectra® fibre reinforcements, the Breach Jacket's design is based on the Summit Suit worn by Co-Founder Staz on his Mission: Everest record.

The main body is constructed from Pertex® Quantum Pro fabric in a Diamond Fuse construction, lightweight and packable with increased abrasion resistance and superior water shedding, while the yoke and outer sleeve carry Spectra® fibre (UHMWPE) ripstop reinforcement, downproof and windproof, with roughly three times the tear strength of conventional synthetic fabrics. Insulation comes from 850 fill power white goose down (90% down, 10% feather) with reduced panelling and box-wall baffle construction to minimise cold spots, reinforced by PrimaLoft® Black Rise at the chest, waist pocket and front placket. The hood carries a reinforced, pliable peak and cord-lock adjusters at back and hem for a clean fit. The centre front uses a YKK® 2-way Vislon® zip with branded puller and zip guard; chest and hidden hip pockets use YKK® Vislon® zips set behind the down fill. A RECCO® reflector sits at the hood peak for rescue visibility.

BEYOND ENDURANCE

BUILT FOR THE LONG HAUL

When movement slows and temperatures plummet, retaining warmth becomes critical. The Breach Jacket is purpose-built for prolonged periods of inactivity in extreme cold, providing dependable insulation when the body can no longer rely on movement to generate heat. Designed for those who venture further, stay longer and refuse to be dictated by the conditions.

STRENGTH WITHOUT THE WEIGHT



Extreme warmth shouldn't come at the expense of freedom of movement. The Breach balances exceptional insulation with lightweight, reinforced construction, delivering protection without unnecessary bulk. Every element is considered to withstand demanding alpine conditions while maintaining the comfort and mobility needed to push further.
