A real waterproof that weighs almost nothing
Outdoor Research Helium Rain Jacket
Pertex Shield, ~180 g, packs into its own pocket
Light enough that you actually carry it, which is the only property that matters in a shell — the trade is a thin fabric that will not survive being dragged across rock.
So light it lives in the daypack unnoticed
Properly waterproof, not water-resistant
Packs to the size of a fist
Delicate face fabric
Minimal ventilation — you will sweat inside it
No pit zips
Not for you if: Monsoon-season trekking where you will be in rain for hours daily. Take a heavier three-layer shell with pit zips.
