If a lightweight, compact, waterproof breathable shell is paramount to your next alpine objective, the Mountain Hardwear Quasar is the ticket to the top. This ultralight climbing shell packs a fully waterproof, highly breathable, and well-featured hardshell into a mere 9.5 ounces. Whether it's in your pack or over your body the Quasar is so light, so compact, and so comfortable you'll hardly notice it.
But the Quasar is not even remotely durable. After four months of use our test model was riddled with tears and holes. After washing it once the hang loop delaminated! Consequently, we prefer the Arc'teryx Alpha FL becuase it provides a more durable jacket with a full-length zipper and helmet compatible hood, all for only 1.2 ounces more.
