Our Verdict

The Mountain Equipment Oreus Hooded Insulated Jacket has made waves this year, winning the prestigious IPOS award for innovation in outdoor clothing. It has to be my favourite synthetic jacket of the year. Designed with Mountain Equipment’s exclusive Aetherm insulation, the Oreus provides exceptional warmth-to-weight ratio, loft, and packability, making it one of the brand’s lightest and most compressible insulated options.

Weighing in at 397g for a medium, this jacket is crafted with recycled 10D Plasma fabric, which is both windproof and treated with an FC-free DWR for added weather protection. The Aetherm insulation, constructed of multiple strands of recycled polyester fibres within a heat-reflective layer, resists moisture, keeping you warm in damp or unpredictable weather.

The Oreus features a fully adjustable Mountain HC Hood, two hand-warmer pockets, a Napoleon chest pocket, and a pleated internal drop pocket for gloves, hats, etc. The 2-way front zip and rear insulated baffle ensure warmth without compromising mobility, and the elasticated cuffs and dual tether hem drawcords keep the fit close against the elements.
