You’re out enjoying winter, taking in crisp air and treading on fresh snow. Then the wind kicks up. The snow turns to sleet. And you? Still enjoying it all, if you’re in a weatherproof Ursa Major Jacket. It packs warmth in spades, with lofty 650-fill-power down insulation. The light-yet-durable shell has fully sealed seams and a waterproof/breathable barrier to lock out water and stop wind cold. Loaded with details you’ll appreciate in bitter cold, like a head-hugging hood liner and draft-stopping collar that help minimize heat loss. With zoned synthetic insulation where you sweat most, plus pit zips to keep you from overheating on a hike. It all works together to mark a major step forward in comfort when all else is icing over.
