Sound like a gimmick? Nope. Our patented SOLARCORE® insulation provides more warmth than traditional down jackets, without the annoying puffy bulk. It's time to ditch the down. Forbes Magazine calls the Orion Parka "The Warmest Jacket on Earth" for a reason. It is.

OROS is the anti-layering brand. That means you can get more warmth, with less. Less bulk and less layers, so you can do more.

Our ultra-thin SOLARCORE® insulation holds heat better than any bulky down or synthetic, so you’re never left out in the cold.

OROS jackets are designed from the ground up with maximum warmth, and no bulk in mind. What does that mean for you? Put simply, you don't have to layer anymore. Less layers, more closet space, less waste, and more freedom to move in the way that you want.

Just 2mm of SOLARCORE® insulation can warm you as effectively as the typical overstuffed, expensive down jackets.

Thermal body-mapping techniques target heat sensitive areas for maximum warmth for all-day comfort.

SOLARCORE® is a completely cruelty-free, vegan-friendly alternative to traditional, more expensive goose down jackets.

Polyfluorocarbons (PFCs) are good at repelling water, but bad for the environment. That’s why we use PFC-free DWRs.
