Why We Love the Outdoor Research Helium AscentShell Jacket
When it comes to weight and breathability, the Outdoor Research Helium AscentShell Jacket is our go-to choice for fast-and-light alpine adventures. It outperforms heavier hard shells by combining the lightweight durability of Pertex Diamond Fuse fabric with the air permeable and highly breathable waterproofing of a 3-layer AscentShell membrane. The result is a jacket that is both lightweight and breathable, while also being weatherproof enough to withstand harsh conditions.
Not only does the Helium take up minimal space in our packs, but it also layers easily between our mid-layers, backpacks, and harnesses. This makes it perfect for high-output activities in the mountains.
