Outdoor Research Helium Down Jacket

Retail Cost: $278.95
What Our Gearhead Experts Are Saying:
"The Helium Down Jacket is a must-have for alpine missions. It's incredibly lightweight and warm, and the waterproof reinforcements on the shoulders and sleeves are clutch for unpredictable weather. I love how packable it is—it stows into its own pocket, making it perfect for climbing or backpacking trips."
Engineered for high-altitude performance, the Helium Down Jacket offers the perfect blend of warmth, durability, and packability. Its 800+ fill power goose-down insulation delivers lightweight warmth, while the Pertex Quantum Diamond Fuse shell ensures rugged, weather-resistant performance. Strategic reinforcements with Pertex Shield on the shoulders and upper sleeves protect against moisture, while an array of pockets—including one that doubles as a stuff sack—provides practical storage for gear and essentials. With its streamlined fit and eco-friendly construction, this jacket is a go-to for alpine explorers seeking gear that performs well and protects the planet.
