Outdoor Research Men's Helium Down Jacket

The Outdoor Research Men's Helium Down Jacket is an ultralight, packable insulating layer built for cold-weather alpine performance. Designed as the ultimate alpine insulator, it excels both as a standalone piece and as a mid-layer beneath a hardshell in demanding conditions.

The shell is constructed from Pertex Quantum Diamond Fuse 100% recycled nylon, offering exceptional durability and a featherlight feel. Pertex Shield reinforcement on the shoulders and upper sleeves adds waterproof protection where moisture contact is most likely. Inside, 800+ fill power responsibly sourced down delivers exceptional warmth-to-weight ratio with outstanding compressibility.

Thoughtful storage includes brushed tricot-lined hand pockets, an external chest pocket, and dual internal stash pockets. The left-hand pocket doubles as a stuff sack, allowing the jacket to pack down into itself for easy transport. Additional details include an elastic drawcord hem and Low-Pro Binding for a clean, streamlined silhouette. The jacket weighs approximately 385 grams, making it a highly capable companion for backpacking, ski touring, and alpine climbing.
