Not for: Anyone wanting a tailored trench to wear over a suit, or an ultralight packable shell.

Columbia Watertight II (line)

An affordable, packable waterproof jacket for occasional rain.

Not for: People in long downpours or on strenuous hikes, where it breathes less well.

Marmot PreCip Eco (line)

A light, packable waterproof shell that is a long-standing pick for hikers.

Not for: Anyone who needs a durable shell for heavy daily commuting.

London Fog (brand)

A long-running trench and raincoat maker with styles cut to wear over suits.

Not for: Anyone hiking or facing sustained heavy rain.

Waterproof construction: Needs a waterproof membrane plus fully taped seams; 2.5L for light and packable, 3L for durability Without taped seams, water comes through the stitching.
Waterproof rating: Around 10,000 mm suits moderate rain, and 20,000 mm or more is for sustained heavy rain This is the standard hydrostatic-head measure used for rainwear.
Venting: Pit zips or mesh-lined pockets if you will walk or hike in it They reduce condensation inside the jacket, which feels like leaking.
Hood: Adjustable hood with a stiffened brim An unadjusted hood blows back and lets rain into your eyes.
Trench fabric: A cotton gabardine trench is water-resistant only, not waterproof Classic trenches shed showers but soak through in a downpour.

Usually condensation from sweat or a worn-out DWR coating, not a leak; vent the jacket and re-treat the face fabric.
