Is the Rab Downpour Jacket fully waterproof?

Yes. It uses a 2.5-layer waterproof membrane with taped seams and a water-repellent finish, so it handles sustained rain. It is a shell, not insulation.

How breathable is it for hiking?

Rab rates it at 20,000g breathability, which is high for a light shell. It moves sweat well on moderate effort, though steep climbs can still feel warm without pit zips.

How does it compare with the Rab Kangri?

The Kangri uses a tougher 3-layer fabric with pit zips and a more protective cut. The Downpour is lighter and simpler, better for packing and fast movement, while the Kangri suits colder, wetter mountain days.

What sizes does it come in?

It is a women's fit offered from XS through XL, with US sizes 0 and 8 listed. The cut is slim and straight, so size up if you plan to layer a fleece underneath.

Does it have pockets and a hood?

Yes. It has a hood and hand pockets with zip closures, plus a two-way front zip and press studs. The hood is adjustable for a secure fit in wind.

What is it best used for?

Hiking, climbing and running in wet conditions. It is light enough for running and packable for climbing, but not a substitute for an insulated jacket in cold weather.
